Subject: [PATCH] feat: add client-side R2 to WebTorrent generation flow
Integrates WebTorrent client-side seeding into the Cloudflare R2 upload path.
- Adds `uploadFile` to `r2Service` for generic file uploads.
- Updates `UploadModal` to offer an optional "Create torrent & seed" flow.
- Generates magnet links and .torrent files in the browser after R2 upload.
- Uploads the .torrent file to R2 and populates `xs` tag.
- Populates `ws` (Web Seed) with the R2 public URL.
- Adds UI progress indicators for hashing and torrent upload.
- Enforces a 2GB file size limit for browser seeding to prevent crashes.
- Adds a mandatory legal rights confirmation checkbox for R2 uploads.
