Miscellaneous fixes (#23279)

* use monotonic clock for detector inference duration to prevent negative values from wall clock steps

* add ability to set camera's webui_url from camera management pane

* Gemini send thought signature

* Update docs

* copy face and lpr configs from source camera to replay camera

* add guard

* improve dummy camera docs

* remove version number

* fix stale field message after reverting a conditional form field

Routes field-level conditional messages through a dedicated React Context instead of merging them into uiSchema. RJSF's Form keeps state.uiSchema sticky across renders during processPendingChange (formData is updated, uiSchema is not), so a previously injected ui:messages array stays attached to a field even after the triggering condition flips back to false. Context propagation re-runs FieldTemplate directly on every provider value change, sidestepping that staleness.

* add semantic search field message to note that model_size is irrelevant when embeddings provider is selected
