fix(idaa): audit and harden IDAA module components and types

- Updated ae_types.ts with missing IDAA-specific fields for Archives and Events (topic_name, archive_on, contact_li_json, etc.) using snake_case.
- Refactored bulletin board post filter to safely handle null archive_on dates.
- Fixed missing 'data' prop assignment in bulletin board list component to resolve type error.
- Corrected core_func.download_export__obj_type method name in recovery meetings export.
- Hardened safety checks for contact_li_json in recovery meetings view logic to prevent null property access.
- Mapped Jitsi meeting event data to internal snake_case variables and fixed input type assignments.
- Updated project documentation (TODO, GEMINI.md, .ae_brief) to reflect IDAA hardening progress.
