feat: refine Scan & Taste UI, fix desktop scrolling, and resolve production login fetch error

- Reverted theme from gold to amber and restored legacy typography.
- Refactored ScanAndTasteFlow and TastingEditor for robust desktop scrolling.
- Hotfixed sw.js to completely bypass Supabase Auth/API requests to fix 'Failed to fetch' in production.
- Integrated full tasting note persistence (tags, buddies, sessions).
