feat: add manual translation editing and bidirectional translation

- Replace translation label with editable entry field
- Move translation field next to Bulgarian input for better UX
- Add bidirectional translation support:
  - Bulgarian → English: auto-translate when only Bulgarian provided
  - English → Bulgarian: auto-translate when only English provided
  - No translation when both fields are filled
- Show translations immediately upon generation
- Auto-save translations when edited
- Keep input fields populated during processing
