6a3b8967b4 Frontend: timestamp display enhancement (issue #286) (#291)
## Frontend: Timestamp Display Enhancement

Refs #286 — implements P0 frontend scope from the [final
spec](https://github.com/Kpa-clawbot/CoreScope/issues/286#issuecomment-4158891089).

### What changed

**Shared formatter (`public/app.js`)**
- `formatTimestamp(isoString, mode)` — returns formatted string ("ago"
or absolute)
- `formatTimestampWithTooltip(isoString, mode)` — returns `{ text,
tooltip, isFuture }` for dual-format hover
- `timeAgo()` fixed: null → `"—"`, future timestamps shown with actual
value (not clamped)

**All surfaces updated**
- `public/packets.js` — table rows + detail pane use shared formatter,
hover shows opposite format
- `public/live.js` — fixed inconsistency (`toLocaleTimeString` → shared
formatter), same tooltip treatment
- `public/nodes.js` — node timestamps use shared formatter

**Future clock skew**
- ⚠️ icon shown when timestamp is in the future, tooltip: "Timestamp is
in the future — node clock may be skewed"

**Customizer (`public/customize.js`)**
- New "UI Settings" section with timestamp mode toggle (ago ↔ absolute)
- Labeled as global setting
- Persists to localStorage (`meshcore-timestamp-mode`), falls back to
server default

**CSS (`public/style.css`)**
- `col-time`: min-width + nowrap for ISO timestamps
- Mobile: shorter format (time only) instead of hiding column

### Testing
- `node test-frontend-helpers.js` — formatter unit tests (null, ago,
absolute, future skew)
- `node test-packet-filter.js` — existing tests pass
- `node test-aging.js` — existing tests pass

Cache busters bumped in `public/index.html`.
