Implement unified frontend type system and migrate core modules

- Created src/lib/types/ae_types.ts to serve as the central repository for Aether object interfaces.
- Standardized interfaces to include the triple-ID pattern (id, [type]_id, [type]_id_random) for Dexie and V3 API compatibility.
- Migrated Account and JournalEntry modules to use ae_Account and ae_JournalEntry types.
- Added explicit Promise return types to all core data loading, creation, and update functions in migrated modules.
