API - BTR Daily Bulk Update

- SI's listed in BTR will not be shown for 90 calendar days (starting 1 day after registration)
- This process will update search to display SI's who are no longer required to be hidden
- This will be a cloud schedule that will run a script to update the new records
- Note: these records are available immediately to competent authorities so this will require a new field in SOLR to decide if it's publicly available or not
- includes solr updates, internal api endpoint and cloud schedule trigger

Start by locating the search/SOLR indexing code, the internal API entry point, and the cloud-scheduled job entry point. Trace how BTR registrations are hidden and how competent-authority access is distinguished from public search. Done means records become publicly searchable after 90 calendar days while remaining immediately available to competent authorities.
