fix: use drift-compensating scheduler in recording handler, fix media URL consistency

- Replace setInterval in recording handler with startCursorSampling() so
  the drift-compensating scheduler is used for actual recordings (was missed)
- Pass realpath-resolved path to buildMediaUrl for symlink consistency
- Use resolvedWebcamVideoUrl in thumbnail/export configs with file:// fallback
