Implement Phase 6 of the roadmap - NoteType list page with CRUD modals:
- NoteTypesPage displays all user's note types with templates and reversible badge
- CreateNoteTypeModal for creating new note types with templates
- EditNoteTypeModal for updating existing note types
- DeleteNoteTypeModal with constraint warning
- Navigation link from HomePage header
- Comprehensive tests for all components (65 new tests)
