ShareLinks: only inject the ShareLink button into real item action sheets

The fallback injector matched almost any dialog with a couple of buttons,
so the button leaked into the Edit images and Add to collection dialogs
(both opened from the item menu). Restrict it to genuine action sheets
(.actionSheet / [role=menu]) whose entries are .actionSheetMenuItem and
include a recognizable item command, which also excludes audio/subtitle/
quality pickers. The primary path (next to Copy Stream URL) is unchanged.
