Add watchdog agent profile to command center

- Add 'watchdog' to KNOWN_PROFILES (5th agent)
- Custom status check via watchdog state file + kanban gateway fallback
- New /api/watchdog/status endpoint with scripts, plugins, heartbeat info
- Watchdog endpoint bypasses auth (public, non-sensitive)
- Update frontend PROFILE_ICONS + cache buster
