Bug ID: 43269
Summary: Add cached description_for() class methods to
Koha::Libraries, Koha::ItemTypes,
Koha::Patron::Categories

Severity: enhancement

Target Milestone: ---
Several places in Koha need to resolve codes to human-readable descriptions
(branchcode to library name, categorycode to category description, itype to
item type description). Currently this is done either per-row via
Koha::Libraries->find($code)->branchname (uncached, N+1 queries) or via
C4::Biblio::GetAuthorisedValueDesc (cached but MARC-centric API requiring
tag/subfield/framework).
We should add cached class-level lookup methods on the domain objects:
Koha::Libraries->name_for($branchcode);
Koha::Patron::Categories->description_for($categorycode);
Koha::ItemTypes->description_for($itype);
These would:
- Use Koha::Caches to pre-fetch all values for the table on first access
- Return the description string (or the raw code as fallback)
- Be usable from any context (CSV exports, templates, scripts, REST API)
This decouples the caching from the MARC layer and makes it available to the
Koha::CSV subclass pattern (bug 41621) and anywhere else that needs bulk
code-to-description resolution without N+1 queries.
