Settings UI tweaks (#22547)

* fix genai settings ui

- add roles widget to select roles for genai providers
- add dropdown in semantic search to allow selection of embeddings genai provider

* tweak grouping to prioritize fieldOrder before groups

previously, groups were always rendered first. now fieldOrder is respected, and any fields in a group will cause the group and all the fields in that group to be rendered in order. this allows moving the enabled switches to the top of the section

* mobile tweaks

stack buttons, add more space on profiles pane, and move the overridden badge beneath the description

* language consistency

* prevent camera config sections from being regenerated for profiles

* conditionally import axengine module

to match other detectors

* i18n

* update vscode launch.json for new integrated browser

* formatting
