fix: resolve magic scan crash and implement context-aware AI languages

- Fixed SQL syntax error in magicScan caused by single quotes
- Implemented dynamic locale-aware AI suggestions (Technical: EN, Custom Tags: Localized)
- Updated Dexie schema to version 2 (added locale to pending_scans)
- Fixed missing bottle_id in UploadQueue synchronization
- Installed missing dexie dependencies via pnpm
