feat(v1.4.0): Propriétés Avancées — collection_properties, 21 types, API CRUD

- Table collection_properties (21 types Notion: number, checkbox, url, email, phone, status, files, unique_id, ...)
- Auto-propriétés: created_time, created_by, last_edited_time, last_edited_by
- Service property_types.py: validation, formatage, auto-values
- API: GET /db/property-types/api, CRUD /db/{id}/properties/api, PUT/DELETE /db/properties/{id}/api
- 38/38 tests passent (+4 nouveaux tests v1.4)
- Version 1.3.0 → 1.4.0
- Docs: ROADMAP, CHANGELOG, WORKLOAD, README à jour
