Adds DBIC relationship aliases so that +count embeds advertised in
the API specs are backed by actual database relationships, making
them sortable via the SQL COUNT subquery infrastructure.
New aliases:
- Borrower: checkouts (issues)
- Aqbookseller: baskets (aqbaskets), invoices (aqinvoices)
- Ticket: updates (ticket_updates)
- ErmEholdingsPackage: resources (erm_eholdings_resources)
- Biblio: holds (reserves)
Koha methods are updated to use the new relationship names directly,
following the one-liner style: Koha::Foo->_new_from_dbic( scalar ... )
Note: checkouts on Borrower and subscriptions on Aqbookseller already
had matching DBIC relationships. comments on Illrequest, requests on
IllBatch, and items on Biblio also already existed.
Test plan:
1. Apply patch
2. Run:
$ ktd --shell
k$ prove t/Koha/REST/Plugin/Query.t \
t/db_dependent/api/v1/patrons.t \
t/db_dependent/api/v1/acquisitions_vendors.t \
t/db_dependent/Koha/REST/Plugin/Objects.t \
t/db_dependent/Koha/Biblio.t
=> SUCCESS: All tests pass
3. Verify sorting works:
GET /api/v1/patrons
x-koha-embed: checkouts+count
_order_by: -me.checkouts_count
=> SUCCESS: Patrons sorted by checkout count
4. Sign off :-D
