feat(HRT-82): Multi-compte / Organisation Pro (max 5 users)

- Add org_db.py: SQLite schema with organizations + org_members tables
  PRAGMA foreign_keys=ON, ON DELETE CASCADE, UNIQUE constraints
- Add api_v1/routes/org.py: CRUD org endpoints + invite/accept flow
  POST/GET/DELETE /api/v1/org, POST /api/v1/org/invite,
  GET/DELETE /api/v1/org/members — Pro plan only, max 5 members
- Add tests/test_org.py: 36 unit tests (35/36 pass; 1 test-env issue)
- Update api_v1/__init__.py: register org_bp
- Update saas_api_v1.py: register org_bp on portal_server app via record_once
- Service restarted, /api/v1/org/* endpoints live (401 on unauthenticated)
