feat(api): add NoteType and NoteFieldType API routes

Implement REST API endpoints for managing note types and their fields:
- CRUD operations for note types (/api/note-types)
- Field management nested under note types (add, update, delete, reorder)
- Constraint checks to prevent deletion of note types with existing notes
- Constraint checks to prevent deletion of fields with existing values
