Sponsorships
List every sponsorship for the active client
Returns every DonorEntity row for the calling admin’s client, augmented with display names for the entity (via Donor::getEntityName) and the donor (via Entity::getDonorName). Currently scoped via the legacy session client_id rather than the bearer token, so callers must have an active admin session even though the route is also bearer-protected. Mirrored at /admin/all_sponsorships on both v1/admin and the legacy api.php. Requires permission: manage_programs.
