SeekQuote New v0.2.1

- All browser movie recordings now pass through server finalisation, including MP4 recordings from iPhone/Safari.
- Forces true constant 30fps H.264/yuv420p output rather than accepting a nominal 30fps variable-frame-rate iPhone MP4.
- Send to Phone uses the same CFR finalisation.
- Keeps the browser recording as a fallback if server finalisation is temporarily unavailable.
- Cache-busts editor-app.js so the new export code loads immediately.
