- Added session log documenting Web-App stabilization, including fixes for Webpack build and login issues.
- Implemented full-sync workaround in `PingEventRepositoryImpl` due to SQLDelight async driver limitations.
- Updated `PingDashboard` to display sync completion messages.
- Added `libs.sqldelight.coroutines` dependency and regenerated SQLDelight queries.
- Updated roadmap and journal with progress on frontend sync integration.
