fix: resolve API errors and browser warnings on dashboard

- Add mobile-web-app-capable meta tag to layout head (fixes deprecated
  apple-mobile-web-app-capable browser warning)
- Set preload:false on Syne and JetBrains Mono fonts; add display:swap
  to Inter (fixes 'preloaded but not used within a few seconds' warnings)
- Wrap wakatime route in try/catch; return hasData:false instead of
  crashing (fixes 404/500 when supabase unavailable or user not found)
- Notifications, local-coding/stats, github-accounts: return empty data
  instead of 500 when table doesn't exist in schema (graceful degradation)
