Fixes (#18338)

* improve spacing of face selection in mobile drawer

* fix spacing

* sort face names alphabetically

* Improve face selection dialog

* Use a state to track when face image loads

The naturalWidth and naturalHeight will always be 0 until the image loads. So we use onLoad and a state to track loading and then calculate the area after it has loaded

* Verify that a camera only tracks objects that are possible to track

* Fix test

* genai docs tweak

* Disable openvino model cache

* Clenaup

* Sanitize floats for estimated speed and angle

Users can configure speed zones in such a way that velocity estimates from Norfair cause a value of inf to be stored as an estimated speed. FastAPI doesn't serialize inf as a float, so trying to return this value would result in an API error. Sanitizing the value before storing should correct this.
