fix(standardization): enforce V3 String-Only ID mapping and harden account isolation

- Added 'account_id_random' to persistent property list to fix local search isolation.
- Standardized search body and helpers to support mandatory x-account-id headers.
- Refactored LiveQuery to use synchronous dependency tracking ($derived.by) for reliable search updates.
- Broadened server-side search to handle inclusive OR logic on the client, preventing disappearing results.
- Updated task list with IDAA Recovery Meeting testing status.
