fix(idaa): resolve BB comment loop and parent mapping issues

- Switched to create_nested_obj_v3 for establishing parent-child links.
- Optimized background load trigger with untrack to prevent infinite loops.
- Resolved MySQL IntegrityError (missing post_id) during comment creation.
- Hardened view component reactivity for Svelte 5.
