- **Core Updates:**
- Implemented `P2pSyncService` interface with platform-specific WebSocket implementations (`JvmP2pSyncService` and no-op for JS).
- Developed `SyncEvent` sealed class hierarchy to handle peer synchronization events (e.g., `PingEvent`, `PongEvent`, `DataChangedEvent`, etc.).
- **Frontend Integration:**
- Introduced `SyncManager` to manage peer discovery and synchronization, coupled with `NetworkDiscoveryService`.
- Updated dependency injection to include `syncModule` for platform-specific sync service initialization.
- Enhanced `BewerbViewModel` to support new sync capabilities, including observing sync events and UI updates for connected peers.
- **Backend Enhancements:**
- Added ZNS-specific fields (`zns_nummer`, `zns_abteilung`) to Bewerb table for idempotent imports.
- Introduced import ZNS logic to handle duplicates and align with SyncManager updates.
- **UI Improvements:**
- Enhanced `TurnierBewerbeTab` with updated dialogs (ZNS imports, sync status) and dynamic previews.
- Improved network syncing feedback and error handling in frontend components.
- **DB Changes:**
- Added migration for new column fields in the Bewerb table with relevant indexing for ZNS import optimizations.
