feat(gui): add OriginManagerDialog for managing file origins (#15)

- Create OriginManagerDialog with list of configured origins
- Show connection status for remote origins
- Allow setting default origin
- Add/Edit/Remove buttons (Add/Edit show placeholder for now)
- Wire up 'Manage Origins...' button in OriginSelectorWidget
- Prevent removal of built-in local origin

Part of Issue #15: Multi-instance Silo configuration UI
