Tweaks (#22965)

* use ffmpeg to probe rtsp urls instead of cv2

cv2 is faster (no subprocess launch) and will continue to be used for recording segments

* tweak faq

* change unsaved color to orange

avoids confusion with validation errors (red)

* don't use any variant of orange as a profile color

avoids confusion with unsaved changes

* more unsaved color tweaks

 You can still configure Frigate to use UDP by using ffmpeg input args or the preset `preset-rtsp-udp`. See the [ffmpeg presets](/configuration/ffmpeg_presets) documentation.
 
-### Frigate hangs on startup with a "probing detect stream" message in the logs
+### Frigate is slow to start up with a "probing detect stream" message in the logs
 
-On startup, Frigate probes each camera's detect stream with OpenCV to auto-detect its resolution. OpenCV's FFmpeg backend may attempt RTSP over UDP during this probe regardless of the `-rtsp_transport tcp` in your `input_args` or preset. For cameras that do not respond to UDP (common on some Reolink models and others behind firewalls that block UDP), the probe can hang indefinitely and block Frigate from finishing startup, or it can return zeroed-out dimensions that show up as width `0` and height `0` in Camera Probe Info under System Metrics.
+When `detect.width` and `detect.height` are not set, Frigate probes each camera's detect stream on startup (and when saving the config) to auto-detect its resolution. For RTSP streams Frigate probes with ffprobe and automatically retries over TCP if UDP doesn't respond, with a 5 second timeout per attempt. A camera that cannot be reached over either transport will add up to ~10 seconds to startup before Frigate falls through with default dimensions, which may show up as width `0` and height `0` in Camera Probe Info under System Metrics.
 
-There are two ways to avoid this:
+To skip the probe entirely and make startup instant, set `detect.width` and `detect.height` explicitly in your camera config:
 
-1. Set `detect.width` and `detect.height` explicitly in your camera config. When both are set, Frigate skips the auto-detect probe entirely:
-
-   ```yaml
-   cameras:
-     my_camera:
-       detect:
-         width: 1280
-         height: 720
-   ```
-
-2. Force OpenCV's FFmpeg backend to use TCP for RTSP by setting the environment variable on your Frigate container:
-
-   ```
-   OPENCV_FFMPEG_CAPTURE_OPTIONS=rtsp_transport;tcp
-   ```
-
-   This is a process-wide setting and applies to all cameras. If you have any cameras that require `preset-rtsp-udp`, use option 1 instead.
+```yaml
+cameras:
+  my_camera:
+    detect:
+      width: 1280
+      height: 720
