feat(config): add missing dictionary item CRUD, setting delete, and numbering delete routes

- Dictionary items: POST/PUT/DELETE endpoints under /config/dictionaries/{dict_id}/items
- Settings: DELETE /config/settings/{key}
- Numbering rules: DELETE /config/numbering-rules/{id}
- Fix workflow Entities: add deleted_at and version_field to process_definition,
  add standard fields to token and process_variable entities
- Update seed data for expanded permissions
