fix: instant cookie probe, default Auto quality, consistent control order

- Trigger a stream probe immediately when the upstream cookie field changes,
  instead of waiting for the next monitor cycle
- Remove the probeActive guard in checkLinkRow so a cookie-triggered probe is no
  longer dropped when it lands while the URL probe is still in flight (the
  probeToken check already handles superseded results)
- Default the HLS resolution menu to its "Auto" (ABR) entry rather than landing
  on a fixed (lowest) rung; start hls.js in auto level mode
- Keep source (视角) selector on the left and resolution on the right in both
  live and archive players, which previously rendered in opposite order
