Migrate Content and Storage modules to unified type system

- Added ae_HostedFile, ae_HostedFileLink, ae_DataStore, ae_Post, ae_PostComment, ae_Page, ae_Archive, and ae_ArchiveContent to ae_types.ts.
- Replaced local interfaces in core__hosted_files.ts and core__data_store.ts with unified imports.
- Replaced local interfaces in ae_archives/*.ts with unified imports.
- Standardized Promise return types for all core data loading, creation, search, and update functions across migrated modules.
- Synchronized storage and archival modules with Backend V3 field naming and Triple-ID patterns.
