Standardize Core UI forms and unify schemas for V3 API compatibility

- Implement new Svelte 5 Person, Address, and Contact form components with surgical payload logic.
- Refactor core routes (People, Addresses, Contacts) to support unified Create/Edit workflows.
- Update ae_types.ts, db_core.ts, and db_journals.ts to align with V3 backend object models.
- Fix type safety issues in Journal history views and refine metadata display.
- Migrate person core functions to the newer ae_core__person module.
