Pull Request Description

Summary

Fladder now treats a multi-part movie or episode as one logical item across the details page, player queue, progress tracking, and offline downloads.

Added

• Multi-part detection using Jellyfin’s PartCount and AdditionalParts APIs.
• Parts row on movie and episode detail pages, showing each part’s artwork, runtime, progress, and watched state.
• Direct part playback — tapping Part 2, 3, etc. starts that part at its own saved position.
• Queue continuity — after a part ends, the next part is queued automatically; after the final part, playback continues to the next episode.
• Next part label in the player’s next-up overlay.
• Aggregate progress and resume — combined runtime and progress across all parts, with resume landing on the correct part.
• Logical completion — the parent item is marked watched only after the final part finishes; all additional parts are marked watched too.
• Rewatch reset — starting a completed multi-part item over resets the parent and every part.
• Offline multi-part support:
  • Downloading a multi-part movie or episode downloads all of its parts.
  • Parts appear in the Parts row while offline.
  • Offline playback auto-advances through parts and then to the next downloaded episode.
  • Aggregate progress and played state are stored locally and pushed to the server when connectivity returns.
• Automatic database migration from sync schema v1 to v2, adding part metadata columns while preserving existing downloads.

Upgrade note

Existing multi-part downloads need one online refresh/re-sync to acquire their additional parts. The schema migration itself works offline and keeps existing single-file downloads valid.
