fix: recover cached XboxUnity game names

[TrapEmAll]

Summary

• resolves library names directly from the cached XboxUnity catalog when the primary title row is blank, unknown, or repeats its TitleID
• applies the same fallback to library search and the game detail pane
• enriches matching library rows after every catalog page instead of waiting for all pages to finish
• records page-level catalog sync progress
• marks abandoned running syncs as interrupted when a new refresh begins
• repairs already-cached unknown names whenever the database starts
• preserves user-provided and higher-quality known names

Root cause

The catalog cache correctly contained 53510804 as Hitman: Absolution, but the local refresh had stopped after 4,800 of 5,159 titles. Name enrichment ran only after all 52 pages completed, leaving the existing library row blank despite the correct title already being cached.

Validation

• reproduced against the user's local database
• confirmed both Library list and details resolve 53510804 as Hitman: Absolution
• safely repaired the existing row with XboxUnity title catalog provenance
• 74 tests passed
• Ruff passed across the repository
• focused mypy checks passed
• compileall and diff checks passed
• tests cover interrupted refreshes, page-level progress, read-through fallback, startup recovery, and preservation of preferred names

Transport

XboxUnity access remains explicitly HTTP-only.
