Initial commit: nimforum with BaraDB backend

- Replaced SQLite with BaraDB via TCP wire protocol
- Added baradb_client.nim and baradb_sqlite.nim adapter
- Renamed SQL keywords: status->usrStatus, key->sessionKey, like->postLike
- Added NOW() support for datetime defaults
- Switched Jester to asynchttpserver (-d:useStdLib) to avoid thread/GC issues
- Frontend built and favicon added
