Miscellaneous fixes (#23258)

* render orphaned filter entries as collapsibles instead of the Key/Value editor

* Symlink for various AI files

* change replay confg dialog to platform aware sheet

* change agents title

* fix test

* tweak collapsible

* remove camera ui section in settings

no point to having it anymore with profiles and camera management settings

* fix admin response cache leak to non-admin users via nginx proxy_cache

* add model fetcher endpoint for genai config ui
