Miscellaneous fixes (#20833)

* remove frigate+ icon from explore grid footer

* add margin

* pointer cursor on event menu items in detail stream

* don't show submit to plus for non-objects and if plus is disabled

* tweak spacing in annotation settings popover

* Fix deletion of classification images and library

* Ensure after creating a class that things are correct

* Fix dialog getting stuck

* Only show the genai summary popup on mobile when timeline is open

* fix audio transcription embedding

* spacing

* hide x icon on restart sheet to prevent closure issues

* prevent x overflow in detail stream on mobile safari

* ensure name is valid for search effect trigger

* add trigger to detail actions menu

* move find similar to actions menu

* Use a column layout for MobilePageContent in PlatformAwareSheet

 This is so the header is outside the scrolling area and the content can grow/scroll independently. This now matches the way it's done in classification

* Skip azure execution provider

* add optional ref to always scroll to top

the more filters in explore was not scrolled to the top on open due to the use of framer motion

* fix title classes on desktop
