add transcoded live streams and stream ordering for auto mode

Cameras can now add lower quality live streams that go2rtc transcodes to H.264 on demand. `live.transcode` takes a source stream and a list of heights and bitrates, and each quality becomes a `{camera}_transcode_{height}p` stream. The config validator adds them to `live.streams` without moving any the user already placed, and drops them when transcoding is disabled or a height changes. `create_config.py` writes them into go2rtc's generated config at startup, and saving the config or deleting a camera syncs them through go2rtc's API, so no restart is needed. They use `#hardware`, so go2rtc picks a hardware encoder and falls back to the CPU when there isn't one.

The Live playback settings stream list can be reordered by drag, since its order is the auto ladder. Auto order sorts it by bitrate, measuring native streams through a new admin-only `/go2rtc/streams/{name}/bitrate` endpoint and using the configured bitrate for transcoded ones. A pure reorder wasn't saved before because RJSF, the settings form, and `update_yaml` all ignore map key order. Sections can now mark a map with `orderedMaps`, which sends the whole map with `replace_paths` so `config_set` rewrites it in order.

Transcoded streams aren't in `go2rtc.streams`, which only lists yaml streams, so the frontend treated them as not restreamed and fell back to jsmpeg. Every restream check now goes through `isRestreamedStream`.

Auto treated any stall with no bytes in the last 2 seconds as a dead camera and handed it to the error fallback, which went straight to jsmpeg. Heavy congestion can stop delivery completely, so congested viewers skipped every lower stream. Auto now declines only when stats show the camera offline, and a stall on a live camera steps down. The stream picker also has a Try highest quality button that sends auto back to the top stream.

+## Apple Silicon Mac (lighter)
+
+[lighter](https://github.com/fieldwork-ai/lighter) is an open-source container runtime for macOS. It gives a container the Mac's media engine as a standard V4L2 decoder, backed by VideoToolbox, so Frigate decodes H.264 and H.265 streams in hardware with the ffmpeg it already ships. It works on M1 and newer Macs with lighter 0.9.2 or newer.
+
+Give the container the video device. With Docker Compose:
+
+```yaml {4-5}
+services:
+  frigate:
+    ...
+    devices:
+      - lighter.sh/video=all
+```
+
+Or with `docker run`, add `--device lighter.sh/video=all`.
+
+Then set the preset for the codec your cameras stream. The decoder is specific to the codec, so if your cameras mix H.264 and H.265, set the preset for the most common codec globally and override it on the other cameras:
+
+```yaml
+ffmpeg:
+  hwaccel_args: preset-apple-silicon-h264
+
+cameras:
+  garage: # an H.265 camera
+    ffmpeg:
+      hwaccel_args: preset-apple-silicon-h265
+```
+
+The presets decode on the media engine and encode the Birdseye restream and timelapses there too. Scaling to the detect resolution runs on the CPU, as ffmpeg's V4L2 decoders cannot scale.
+
+lighter can also run object detection on the Mac's Neural Engine; see [Apple Neural Engine (lighter)](object_detectors.md#apple-neural-engine-lighter).

Setting the streams list will populate a dropdown in the UI's Live view that allows you to choose between the streams. This stream setting is _per device_ and is saved in your browser's local storage. When a camera has more than one stream, the dropdown also offers **Auto**, which is used until you pick a specific stream. Auto starts on the first stream, steps down the list when your connection can't keep up, and steps back up when it recovers. To retry the top stream right away, select **Try highest quality** under the stream picker. List streams from highest to lowest quality, and avoid names that are plain numbers (such as `720`), which the browser sorts ahead of the others. In the UI, drag streams to reorder them, or use **Auto order** to sort them by measured bitrate.

+### Transcoded streams
+
+When a camera has no suitable sub stream, Frigate can add lower-quality streams that go2rtc transcodes to H.264 while someone is watching. They appear in the stream list like any other stream, so Auto mode can step down to them. Enable them under <NavPath path="Settings > Camera configuration > Live playback" />, or in YAML:
+
+```yaml
+cameras:
+  test_cam:
+    live:
+      transcode:
+        enabled: true
+        source: test_cam # optional, defaults to the first live stream

+            bitrate: 1200 # kbps
+          - height: 480
+            bitrate: 500
+```
+
+Each quality becomes a go2rtc stream named `<camera>_transcode_<height>p`. go2rtc picks a hardware encoder automatically and falls back to the CPU, which costs CPU for each transcode while it is being watched. Check go2rtc's `api/ffmpeg/hardware` page to see which encoder it found. Using a sub stream as the `source` lowers the cost.
