feat: add silo-aware start panel

Add a SiloStartPanel dock widget that shows connection status, local
checkouts, recent silo activity, and local recent files. Automatically
shown when the Silo workbench is activated.

Sections:
- Connection status badge (green/gray dot with hostname)
- My Checkouts: scans local projects dir for .FCStd files, shows part
  number and description, double-click to open
- Recent Silo Activity: fetches from server, badges items present
  locally, double-click to open or checkout
- Local Recent Files: reads FreeCAD MRU list, double-click to open

Auto-refreshes every 60 seconds. Panel is reused if already open.

Closes #5
