Pass pgcql.Query for patron requests

[adamdickmeiss]

Should ParsePatronRequestsCQL be part of the PrRepo interface?

[Copilot]

Pull request overview

This PR refactors patron request listing/faceting to pass a parsed pgcql.Query through the repo layer (instead of passing raw CQL strings), so CQL parsing/validation happens at API boundaries and the repo only consumes validated SQL fragments/args.

Changes:

• Update PrRepo interfaces and implementations to accept pgcql.Query for listing patron requests/search view and fetching facets.
• Export ParsePatronRequestsCQL and update API handlers/tests to parse CQL before calling repo methods.
• Adjust the facets SQL template to use parameterized LIMIT/OFFSET so facet queries can safely prepend base args.
