Migrate Posts and Event Presentations to unified type system

- Integrated ae_Post, ae_PostComment, ae_Page, and ae_Archive types into logic files.
- Replaced local interfaces in ae_posts__post.ts and ae_posts__post_comment.ts.
- Standardized Promise return types for all CRUD and loading functions in Post and Presentation modules.
- Synchronized event presentation logic with V3 triple-ID patterns.
