Isaac Connor bf82278b6e feat: integrate EventStream into montagereview with zms recovery and fixes ...

- Integrate EventStream.js into montagereview.js for persistent MJPEG
  streaming in replay mode (speeds >= 1x), falling back to per-frame
  mode=single for speeds < 1x where zms lacks slow-motion support
- Add EventStream recovery logic: detect zms death via AJAX failures,
  img.onerror, and error responses; auto-restart with new connkey and
  exponential backoff (max 5 retries)
- Fix zms crash on bulk/interpolated frames: add stat() check in
  sendFrame() for SaveJPEGs & 1 path, fall through to ffmpeg_input
  when JPEG file doesn't exist on disk; send "No frame available"
  text frame instead of terminating when no source available
- Center monitor canvases: text-align in CSS for scale mode,
  horizontal offset calculation in maxfit2() for fit mode
- Reduce console noise: comment out high-frequency debug logs,
  convert error-path logs to console.warn/error
- Fix ESLint sourceType to "script" for traditional non-module JS
  files, resolving false-positive no-unused-vars on global functions
