Switch clothing fetch to itemconfiguration API, remove load more

- Replace catalog search (1000 item cap) with itemconfiguration/v1/creations/get-assets
- Batch-enrich with catalog/items/details and fetch thumbnails concurrently
- Compound base64 cursor handles shirts then pants pagination
- Add retry logic with backoff for all three Roblox API calls
- Remove load more button; auto-load all pages on group select
- Default sort to newest first
