Kpa-clawbot 3bdf72b4cf feat: clock skew UI — node badges, detail sparkline, fleet analytics (#690 M2+M3) (#752) ...

## Summary

Frontend visualizations for clock skew detection.

Implements #690 M2 and M3. Does NOT close #690 — M4+M5 remain.

### M2: Node badges + detail sparkline
- Severity badges (⏰ green/yellow/orange/red) on node list next to each
node
- Node detail: Clock Skew section with current value, severity, drift
rate
- Inline SVG sparkline showing skew history, color-coded by severity
zones

### M3: Fleet analytics view
- 'Clock Health' section on Analytics page
- Sortable table: Name | Skew | Severity | Drift | Last Advert
- Filter buttons by severity (OK/Warning/Critical/Absurd)
- Summary stats: X nodes OK, Y warning, Z critical
- Color-coded rows

### Changes
- `public/nodes.js` — badge rendering + detail section
- `public/analytics.js` — fleet clock health view
- `public/roles.js` — severity color helpers
- `public/style.css` — badge + sparkline + fleet table styles
- `cmd/server/clock_skew.go` — added fleet summary endpoint
- `cmd/server/routes.go` — wired fleet endpoint
- `test-frontend-helpers.js` — 11 new tests
