Enhance API robustness: Add model validators, view-field filtering, and test suite.

- Added validators to Person_Base, Journal_Base, Journal_Entry_Base, Address_Base, and Contact_Base to handle null values and unsafe lookups.
- Implemented 'fields_to_exclude_from_db' ClassVar in Journal models to prevent view-only fields from causing DB errors.
- Updated Contact object map to align with DB schema.
- Added comprehensive test suite in 'tests/' directory (model validation, filtering logic).
- Updated GEMINI.md with progress.
