Nexview 0.30.1

A hotfix for the Jellyfin sync, from Issue #7: a report with logs and four measurements that pinned the cost down to a single query. Seventeen minutes become about half a minute, a slow query no longer takes the library with it, and two syncs no longer run side by side.

Fixed

Played titles are fetched in one request per account, not page by page. Jellyfin 10.11 evaluates the played filter over the whole library for every page, so the price is per request, not per title. Measured on the reporter's server: a page of 25 played episodes took 45 seconds, everything at once 25. Nexview asked for 19 pages, 17 minutes per account and per run, and the smaller pages it fell back to made every page dearer. It now asks once, without the total count and without image data, and waits up to three minutes for the answer. If the answer does not come, that account skips a round; the library is read regardless.

A failing played-episodes query no longer throws the whole library away. Nexview asks Jellyfin which episodes the stored account has played, and only to mark series as started. When that one query timed out, the entire library read was discarded, and the card said "Not synced yet" for weeks although movies and series themselves arrived in three seconds. The library is now read regardless. Series keep the watched flag from the previous run instead of losing it, and the log names the query that gave up.

"Sync now" no longer runs alongside the hourly sync. Pressing it during the hourly run started a second, identical sync in parallel: the same questions to the same server twice, and two runs writing the same rows. The button now waits for the running sync and reports its result. If that run failed for the server on that page, the button shows the error.

Emby shares the adapter and gets the same three changes; it never showed the problem, because it answers the played query in milliseconds. Plex is not affected.
