151 support for ror identifiers

[amadulhaxxani]

Problem description

The frontend did not support ROR identifiers for publisher fields. While the author field (with ORCID) already used authority values for search links and displayed the ORCID icon, the publisher field only used plain text values for search links and had no visual indicator for ROR.

When the backend added ROR authority support, the publisher search link still used equals operator with the text value, not the authority operator with the ROR ID. The frontend also lacked a ROR icon to indicate that the publisher has a ROR authority.

Analysis

The publisher field uses a different component and data-extraction path than the author field:

• Author uses type="author" → ClarinItemAuthorPreviewComponent → loadItemAuthors → iterates over item.allMetadata(fields) (preserves authority).
• Publisher uses type="search" → inline *ngFor loop in ClarinGenericItemFieldComponent → getLinkToSearch() → calls item.firstMetadataValue() (loses authority).

As a result, getLinkToSearch always built the search URL with ,equals and never checked for authority. The search result cards (using ds-clarin-item-box-view) also used firstMetadataValue() and ignored authority.

Pull request overview

Adds frontend support for ROR-backed publisher metadata by preserving and using authority values when building publisher search links, and by displaying a ROR icon when a publisher authority is present.

Changes:

• Add a ROR SVG icon asset and render it next to authority-backed publisher values.
• Update publisher search link construction to use ,authority with the authority ID instead of ,equals with the plain text value.
• Update generic “search” item-field links to prefer authority when available.
