fix(profile): remove deprecated AT Protocol event source toggle (#369)

The "Use AT Protocol as event source" toggle is now obsolete.
All public events are automatically published to AT Protocol
when the user has an AT Protocol identity.

Removes:
- The Bluesky settings q-card from profile page
- useBlueskyConnection composable (no longer used)
- Related tests for the removed UI

The API-side preferences.bluesky.connected is retained for
backwards compatibility with the legacy Bluesky import feature.
