Add dynamic configuration for more fields (#22295)

* face recognition dynamic config

* lpr dynamic config

* safe changes for birdseye dynamic config

* bird classification dynamic config

* always assign new config to stats emitter to make telemetry fields dynamic

* add wildcard support for camera config updates in config_set

* update restart required fields for global sections

* add test

* fix rebase issue

* collapsible settings sidebar

use the preexisting control available with shadcn's sidebar (cmd/ctrl-B) to give users more space to set masks/zones on smaller screens

* dynamic ffmpeg

* ensure previews dir exists

when ffmpeg processes restart, there's a brief window where the preview frame generation pipeline is torn down and restarted. before these changes, ffmpeg only restarted on crash/stall recovery or full Frigate restart. Now that ffmpeg restarts happen on-demand via config changes, there's a higher chance a frontend request hits the preview_mp4 or preview_gif endpoints during that brief restart window when the directory might not exist yet. The existing os.listdir() call would throw FileNotFoundError without a directory existence check. this fix just checks if the directory exists and returns 404 if not, exactly how preview_thumbnail already handles the same scenario a few lines below

* global ffmpeg section

* clean up

* tweak

* fix test
