test: unify frontend test runs and prevent inventory drift (#1965)

Make `test-all.sh` the authoritative standalone frontend runner for npm
and CI. Restore stale assertions and reject missing, duplicate, removed
or undocumented inventory entries.

Fixes #1858.

Rebased onto `a2f039d4`. Retains release-routing, map scope-state and
Scope Audit stylesheet tests, adds `test-packets-local-channels.js` to
the sorted runner, and classifies `test-neighbor-map-btn-clip-e2e.js`
under browser. Its separate CI browser step is preserved. Inventory: 280
root suites, 167 standalone, 113 requiring separate setup.

The icon repair fixes two suites red on master:
`test-issue-1648-m2-emoji-scan.js` and
`test-issue-1648-m6-final-sweep.js`. Node/live configured-scope
confirmations now use the existing accessible Phosphor check sprite.
Values, visibility conditions and scanner assertions are preserved.

- Red evidence: `89e45a9` inventory assertions; `4e255df` accessible
confirmation assertion. The latest rebase also reproduced both
unclassified-file failures before adding their entries. This follow-up
only changes runner/classification configuration and counts; no test
files modified.
- Local validation: all 167 standalone suites; 27 M2 browser checks and
16 neighbor geometry checks in Chromium. Syntax, whitespace, PII,
CSS-variable and XSS checks passed.
- Browser coverage includes populated/empty/null configured scopes in
node and live views.
- No new dependencies, requests, application settings or Go changes.
Workflow outside the unit step matches master.
- Windows validation uses process-local UTF-8 settings. Encoding and
node-reach confirmation follow-ups remain separate, as requested.

## Preflight override

External `run-all.sh` is unavailable; applicable repository checks were
run directly.
