Phase 2.1 & 2.2: Manual metadata editing and multiple sources
Implemented manual metadata editing UI:
- Added editable input fields for title (200 chars), subject (300 chars), keywords (500 chars)
- Character counters with warning/danger indicators at 90%/100%
- Real-time validation with visual feedback
- Save and Reset buttons for each file
- Individual file metadata updates via /update-manual endpoint
Implemented multiple metadata sources:
- Added metadata source selector dropdown (Excel, Manual, AI, Import)
- Modified /upload endpoint to handle different metadata sources
- Excel lookup: existing functionality (fastest)
- Manual entry: empty fields for user input
- AI generation: placeholder for Phase 2.3
- Import: placeholder for Phase 2.4
Technical improvements:
- Session-based metadata storage for persistence
- Graceful success/error feedback with visual indicators
- Sanitized metadata input with length limits
- Backup creation before updates
