- Add 'nb' (Norwegian Bokmål) to translation extraction script
This ensures Norwegian translations are properly included when
extracting and updating translation catalogs.
- Improve translation compilation error logging
Add exc_info=True to log full exception tracebacks when translation
compilation fails, making it easier to diagnose issues with missing
or corrupted .mo files.
Fixes issue where Norwegian (norsk) translations were not working
due to missing compiled .mo files. The app will now properly compile
Norwegian translations on startup, and any compilation errors will
be logged with full stack traces for debugging.
