Bitesize Reading Library V4.9.9 — Edition labels and standards fidelity

- UK/US Edition labels no longer prepend a flag emoji, which appeared as duplicated text on some Windows browsers.
- Search diagnostics moved from Discover to Settings > Advanced Catalogue Diagnostics.
- Verified standards in one grade remain visible even when other grades await verification in Catalogue Manager.
- Verified standards from Catalogue Manager's published verified_standard_index also populate an installed resource's Standards view, matched by exact product ID.
- Unverified or draft standards are not counted; selected-only standards still need verification in Catalogue Manager.
- No automatic matching of resource titles to standards (product IDs are authoritative).

For digital games, confirm a verified mapping and matching canonical Product ID in Catalogue Manager if no standards are displayed.

Local library data and installed resources are unchanged by this update.
