fix: Details button opens full-screen node detail on desktop (#778)

The previous fix (#779) used hash navigation for the Details button,
which only re-selected the node in the side panel on desktop. Now the
Details button calls showFullScreenNode() to render the same full-screen
detail view that mobile users see, regardless of screen width.

- Extract showFullScreenNode() from mobile-only init code
- Reuse it for both mobile init and desktop Details button click
- Analytics links still navigate via hash as before
- Update Playwright test to verify full-screen view renders

-## How to run
-
-```
-qa staging              # use the latest plans/v*-rc.md against staging
-qa pr 806               # use plans/pr-806.md if it exists, else latest plans/v*-rc.md
-qa v3.6.0-rc            # use plans/v3.6.0-rc.md
-```
-
-The parent agent loads the qa-suite skill, which reads:
-1. The plan file from `qa/plans/`
-2. Bundled scripts from `qa/scripts/`
-3. The reusable engine + qa-engineer persona from the skill itself
-
-## Adding a new plan
-
-For each release candidate, copy the latest `plans/v*-rc.md` to `plans/<new-tag>.md` and update:
-- The commit-range header (`vN.M..master`)
-- Any new sections for new features in the release
-- The "Test data" section if new fixture types are needed
-- The GO criteria (which sections are blockers)
-
-## Adding a new script
-
-Custom scripts go in `qa/scripts/` with `mode=auto: <script-name>` referenced from the plan. The qa-engineer subagent runs them with two args: `BASELINE_URL TARGET_URL`.
-
-Authoring rules from the qa-suite skill:
-- 4-way error classification: `curl-failed` / `parse-empty` / `shape-diff` / field-missing
-- Distinguish HTTP errors from jq parse failures
-- Don't silence stderr — script bugs must surface
-- Exit code = number of failures

-# Plan: v3.6.0-rc
-
-Targets the changes between v3.5.1 and v3.6.0 candidate (~34 commits).
-
-## Test data
-The qa-engineer should pick concrete test fixtures at run time and include them in the report:
-- **Pivot node pubkey**: pick the top-result from `/api/nodes?limit=20&sort=advert_count` that has `role=repeater` AND a non-zero `totalPaths` from `/api/nodes/{pk}/paths`. Used for sections 5.1, 8.1, 8.2.
-- **Multi-role pubkey** (section 8.6): pick a node whose pubkey appears in BOTH `/api/observers` and `/api/nodes?role=repeater`. If none → mark 8.6 `needs-human`.
-- **Sample packet hash**: `/api/packets?limit=1` → `.packets[0].hash`. Used for sections 3.x.
-- **Channel sample**: pick a channel name from `/api/channels` (if endpoint exists) or scrape `/#channels` page.
-
-Record every fixture used in the final report so failures are reproducible.

-## Sections
-
-### 1. Memory & Load
-| # | Step | Pass criteria | Source | Mode |
-|---|---|---|---|---|
-| 1.1 | Container with **3 GB** limit starts on heaviest available DB | No OOM, steady state under limit. Note: 1 GB cap is unrealistic without `GOMEMLIMIT` and bounded cold-load — see #836 | #806/#836 | human |
-| 1.2 | Hit `/debug/pprof/heap` after Load completes; run `pprof-snapshot.sh` | `unmarshalResolvedPath` absent from top-15 inuse_space; `Load()`-attributed inuse_space ≤ 250 MB on staging-sized DB (~1.5M obs); total heap < 1 GB | #806 | auto: pprof-snapshot.sh |
-| 1.3 | Set tight `MaxLoadMemMB`, restart | Load stops gracefully at budget; server still serves `/api/stats` 200 | #790 | human |
-| 1.4 | Watch `processRSSMB` (from `/api/stats`) vs procfs RSS over ingest+eviction cycles | `processRSSMB` tracks `cat /proc/$(pidof corescope)/status | awk '/VmRSS/{print $2}'` (kB → MB) within ±20% across one full eviction cycle. Note: `storeDataMB` (formerly `trackedMB`) is the in-store packet byte estimate and is expected to be a **subset** of RSS, not equal to it. | #751, #832 | human |
-| 1.5 | Run 30 min under live ingest | Sawtooth heap pattern (≥1 eviction-driven dip), not monotonic ramp | #806/#807 | human |
-
-### 2. API contract
-Run `scripts/api-contract-diff.sh BASELINE_URL TARGET_URL` once. Report the script's exit code; nonzero = failures.
-| # | Step | Pass criteria | Source | Mode |
-|---|---|---|---|---|
-| 2.1 | api-contract-diff baseline vs target | Exit code 0; all endpoints carry `resolved_path` where expected | #806 | auto: api-contract-diff.sh |
-| 2.2 | WebSocket `/ws` carries `resolved_path` on broadcasts | Run JS hook in browser console: `(function(){let n=0,r=0; const W=WebSocket; window.WebSocket=function(...a){const s=new W(...a); s.addEventListener('message',e=>{n++; try{const m=JSON.parse(e.data); if(m && (m.resolved_path !== undefined || (m.observations||[]).some(o=>o.resolved_path!==undefined))) r++;}catch{}}); return s;}; window.__wsCount=()=>({n,r});})()` then navigate to `/`, wait 30s, eval `__wsCount()` — `r` must be ≥ 1 if `n` ≥ 1 | #806 | browser |
-
-### 3. Decoder & hashing
-| # | Step | Pass criteria | Source | Mode |
-|---|---|---|---|---|
-| 3.1 | Recompute content hashes for sample of recent packets vs stored | All match (hash uses payload-type bits only) | #787 | human |
-| 3.2 | Inspect a TRACE packet detail panel | path_json length matches path_sz from flags byte | #732 | browser |
-| 3.3 | Check `hash_size` on transport-route packet AND zero-hop advert | Correct hash_size detected | #747 | browser |
-| 3.4 | Field-table column offsets for transport-route packet | Snapshot of detail panel: each field row has nonzero `offset`/`length` cells AND offsets monotonically increase | #766 | browser |
-| 3.5 | Corrupt advert ingest log check | Rejected, counted, no DB entry | #794 | human |
-| 3.6 | Public channel packet rendering | No empty/garbled decode | #761 | browser |
-
-### 4. Channels (#725)
-| # | Step | Pass criteria | Source | Mode |
-|---|---|---|---|---|
-| 4.1 | Channel list — full message history loads from DB | Past messages persist across reload | #726 | browser |
-| 4.2 | Add custom channel via UI (then remove it as teardown) | Channel appears, encrypted msgs decrypt; teardown removes it cleanly. STAGING ONLY. | #733 | browser |
-| 4.3 | PSK channel add + channel removal (already a self-teardown) | Both work, UI state correct after | #750 | browser |
-| 4.4 | Deep link to encrypted channel without key | Lock message shows | #783 | browser |
-| 4.5 | Undecryptable msgs hidden by default + toggle | Hidden default; toggle shows | #728 | browser |
-| 4.6 | Add-channel button + hint + status feedback | All present | #760 | browser |
-| 4.7 | Filter packets by channel | Functional: filter applies, packet count drops; performance: response time ≤ 500 ms for `/api/packets?channel=<name>&limit=100` (timed via `curl -w '%{time_total}'`) | #762/#763 | browser+auto |
-
-### 5. Clock skew (#690)
-| # | Step | Pass criteria | Source | Mode |
-|---|---|---|---|---|
-| 5.1 | Node detail clock-skew badge + sparkline | Both render | #746/#752 | browser |
-| 5.2 | Analytics fleet clock-skew page | Renders, epoch-0 filtered | #769 | browser |
-| 5.3 | Outlier sample doesn't poison median | Sanity caps respected; severity uses `recentMedianSkewSec` (#789), not all-time `medianSkewSec` | #769/#789 | human |
-| 5.4 | Roles page clock-skew indicator | Renders | #752 | browser |
-
-### 6. Observers
-| # | Step | Pass criteria | Source | Mode |
-|---|---|---|---|---|
-| 6.1 | Observer with no packets in N days disappears after retention sweep | Removed | #764 | human |
-| 6.2 | Analytics observer-graph (M1+M2) | Renders (`#observerGraph` element present at `public/analytics.js:2048-2051`) | #774 | browser |
-
-### 7. Multi-byte hash adopters
-| # | Step | Pass criteria | Source | Mode |
-|---|---|---|---|---|
-| 7.1 | Hash Usage Matrix collision details for all hash sizes | Click cell → colliding pubkeys shown | #758 | browser |
-| 7.2 | Multi-byte adopter table includes all node types | Repeaters, room servers, sensors all present | #767 | browser |
-| 7.3 | Role column reflects multi-byte adoption + advert precedence | For 3 sample multi-byte adopter pubkeys (from #758 matrix), the Role column on `/#nodes` matches the role inferred from their latest advert flags via `/api/nodes/{pk}/health` | #767 | browser |
-
-### 8. Frontend nav & deep linking
-| # | Step | Pass criteria | Source | Mode |
-|---|---|---|---|---|
-| 8.1 | Click node on map/list — URL hash updates, panel opens | Hash matches | #739 | browser |
-| 8.2 | Open saved deep-link to a node | Full-screen detail view opens (post-#823: desktop deep links match the Details-link path) | #739/#823 | browser |
-| 8.3 | Packets page filter URL hash | Reload preserves filters | #740 | browser |
-| 8.4 | Details/Analytics links in node detail panel | Navigate without router glitch | #779/#785 | browser |
-| 8.5 | Neighbor graph slider | Persists across reloads, default 0.7 | #776 | browser |
-| 8.6 | Repeater that's also observer | Single map marker | #745 | browser |
-| 8.7 | Side-panel "Recent Packets" — click any entry, lands on packet detail (no 404), entry text is readable in current theme | DB-fallback works (#827); `.advert-info` has explicit color (#829) | #827/#829 | browser |
-
-### 9. Geofilter & customizer
-| # | Step | Pass criteria | Source | Mode |
-|---|---|---|---|---|
-| 9.1 | Customize → "Open geofilter builder" link | Opens app-served builder | #735 | browser |
-| 9.2 | Build a filter, save, reload (STAGING ONLY; teardown: delete the saved filter) | Persists across reload; teardown removes it | #735 | browser |
-| 9.3 | Geofilter docs page | Renders, content matches behavior | #734 | browser |
-
-### 10. Node blacklist
-| # | Step | Pass criteria | Source | Mode |
-|---|---|---|---|---|
-| 10.1 | Add node pubkey to nodeBlacklist config; restart | Hidden from listings/map/neighbor graph | #742 | auto: blacklist-test.sh |
-| 10.2 | Packets still in DB | Yes (filter not delete) | #742 | auto: blacklist-test.sh |
-
-`blacklist-test.sh` covers both 10.1 and 10.2 in one run. Required env: `TEST_NODE_PUBKEY` (hex, of a real visible node on TARGET), `TARGET_SSH_HOST`, `TARGET_CONFIG_PATH`, `TARGET_CONTAINER`. Optional: `TARGET_DB_PATH` or `ADMIN_API_TOKEN` for §10.2 probe; `TARGET_SSH_KEY` (default `/root/.ssh/id_ed25519`). Mandatory teardown removes the pubkey and verifies the node returns to listings.
-
-### 11. Deploy/ops
-| # | Step | Pass criteria | Source | Mode |
-|---|---|---|---|---|
-| 11.1 | Force-redeploy staging | Container removed cleanly even if `docker run`, not compose. Playwright E2E `Desktop: deep link #/nodes/{pubkey} opens full-screen detail view` passes (updated #833 — was asserting old pre-#823 split-panel behavior). | fa348ef/#833 | human |
-
-## GO criteria
-- Sections 1.2, 2, 3 must all pass — release blockers
-- Section 4 (channels) — any visible regression must be fixed before tag
-- Other sections: file follow-up issues; decide per-item whether to tag with known issues
