fix(gateway): add API fallbacks and connection stability improvements

- Add api-fallbacks.ts with structured fallback data for 6 missing API endpoints
  - QuickConfig, WorkspaceInfo, UsageStats, PluginStatus, ScheduledTasks, SecurityStatus
  - Graceful degradation when backend returns 404
- Add heartbeat mechanism (30s interval, 3 max missed)
  - Automatic connection keep-alive with ping/pong
  - Triggers reconnect when heartbeats fail
- Improve reconnection strategy
  - Emit 'reconnecting' events for UI feedback
  - Support infinite reconnect mode
- Add ConnectionStatus component
  - Visual indicators for 5 connection states
  - Manual reconnect button when disconnected
  - Compact and full display modes

Diagnosed via Chrome DevTools: WebSocket was working fine, real issue was
404 errors from missing API endpoints being mistaken for connection problems.
