- Remove |safe from |tojson in HTML attributes (x-data) - quotes must
become " for browsers to parse correctly
- Update LANG-002 and LANG-003 architecture rules to document correct
|tojson usage patterns:
- HTML attributes: |tojson (no |safe)
- Script blocks: |tojson|safe
- Fix validator to warn when |tojson|safe is used in x-data (breaks
HTML attribute parsing)
- Improve code quality across services, APIs, and tests

SQLAlchemy Error Fix:
- Add .unique() when using joinedload(Company.vendors)
- When eagerly loading collection relationships with joinedload, SQLAlchemy can return duplicate rows
- The unique() method deduplicates results and is required for joined collection loads
Error was:
InvalidRequestError: The unique() method must be invoked on this Result, as it contains results that include joined eager loads against collections
This is a standard SQLAlchemy pattern for handling one-to-many relationships with eager loading.
- Add database migration to make vendor.owner_user_id nullable
- Update Vendor model to support company-based ownership (DEPRECATED vendor.owner_user_id)
- Implement company_service with singleton pattern (consistent with vendor_service)
- Create Company model with proper relationships to vendors and users
- Add company exception classes for proper error handling
- Refactor companies API to use singleton service pattern
Architecture Change:
- OLD: Each vendor has its own owner (vendor.owner_user_id)
- NEW: Vendors belong to a company, company has one owner (company.owner_user_id)
- This allows one company owner to manage multiple vendor brands
Technical Details:
- Company service uses singleton pattern (not factory)
- Company service accepts db: Session as parameter (follows SVC-003)
- Uses AuthManager for password hashing (consistent with admin_service)
- Added _generate_temp_password() helper method
