feat: status dots, priority banners, lt-tags, command palette, activity timeline improvements

- Fix DashboardView asset version (was hardcoded 20260327, now uses config ASSET_VERSION)
- Add lt-dot status indicators on dashboard table rows and ticket view toolbar
- Add lt-tag display for Category/Type in ticket read mode (swaps to select in edit mode)
- Add P1/P2 SLA alert banner with elapsed time, progress bar, per-session dismiss
- Wire command palette (Ctrl+K): global nav + admin links via lt.cmdPalette.init()
- Fix cmdPalette.init() call format (flat array, not nested group objects)
- Improve activity timeline: richer formatAction(), better color coding by event type,
  inline status transitions shown in meta row, icon column added
