Add north/south cameras, remove fullday, add verify-mvt.sh

- sky-cam.conf: CAMERAS now includes east, north, south with staggered
  SCHEDULE_SEASONS times (01:00, 01:30, 02:00); fullday schedules and
  tuning removed
- install.sh: fullday service/timer generation removed entirely
- fullday-video.sh + systemd units: deleted
- montage-mvt.sh: post-build technical checks (duration drift, video/audio
  stream presence) added; notification now includes check results and the
  exact verify-mvt.sh command to run
- verify-mvt.sh: new interactive CLI for montage review — shows checks,
  plays video, deletes source JPEG folders on approval, or re-runs montage
