v2.3.6

Fixed

• Idle cameras no longer keep decoding and converting every frame. When a printer is
  positively idle and nobody is viewing its feed, PrintGuard puts the camera in standby and
  resumes it automatically when printing or viewing starts. RTSP, RTMP and WHEP feeds are pulled
  on demand, while MJPEG, Bambu and device cameras keep their existing browser-compatible H.264
  bridge without running it unnecessarily. Unknown or unreachable printers remain monitored.
• Desktop webcams now preview immediately after registration. The camera stays live while its
  preview connects, then still enters standby after viewing or monitoring stops. Slow desktop
  camera startup no longer leaves orphaned captures running after the window closes.
• Camera and monitor status lights no longer flicker between healthy colours. Camera indicators
  now show stable availability, while monitor indicators stay green when watching and switch red
  only for a genuine defect alert.
• RTSP cameras recover after a damaged stream. If packet loss or decoder errors leave a camera
  offline, PrintGuard now replaces the failed reader and its MediaMTX pull automatically instead
  of retrying the same broken session until the camera is toggled manually.
• Alert-only notifications now state that no printer action is configured. This makes clear that
  detection and push alerts are still active when a printer is powered off or unreachable.
• Printer actions and notifications no longer pause camera inference. Slow or unreachable
  services are handled independently while monitoring continues, and genuinely stalled camera
  sources are replaced automatically after a fresh-frame timeout.
