Fix editing update and dialog state

Ensure editing a game updates the library view and the edit dialog reliably.

- Refresh the model when a Game emits change signals so filtering/sorting stays in sync.
- Reload edit fields on open/game change to avoid stale values after typing.
- Center the edit dialog with an explicit size.
