Refactor: Auth & Identity System v1.4

- Fix: Resolved SQLAlchemy Mapper error for 'UserVehicle' using string-based relationships.
- Fix: Fixed Postgres Enum case sensitivity issue for 'userrole' (forcing lowercase 'user').
- Fix: Resolved ImportError for 'create_access_token' in security module.
- Feature: Implemented 2-step registration protocol (Lite Register -> KYC Step).
- Data: Added bank-level KYC fields (mother's name, ID/Driver/Boat/Pilot license expiry and categories).
- Business: Applied private fleet isolation (is_transferable=False for individual orgs).
- Docs: Updated Grand Master Book to v1.4 and added Developer Pitfalls guide.
