fix: Search results show raw schema/register IDs instead of friendly names

[rubenvdlinde]

Problem

Unified search results show subtitles like Schema: 498 • Register: 228 • Updated: 2026-03-20 instead of human-readable names like Client • Pipelinq.

Expected

Results should show the schema name and register name from the metadata, e.g.:

• "Client • Pipelinq • Updated: Mar 20, 2026"
• "Case • Procest • Updated: Mar 16, 2026"

Location

lib/Search/ObjectsProvider.php — the buildSearchResultEntry() method constructs the subtitle.

Fix

Resolve schema and register names from the result's @self metadata or from the schema/register entities.
