ShareLinks: hide add-to-playlist/collection via robust JS match

The CSS data-id selector wasn't reliably hiding the action-sheet item in
guest sessions, so add a JS pass (part of the lockdown refresh) that
matches menu items by data-id, localized visible text, and icon, and
hides them with an inline style. The action sheet is added on menu open,
which the existing mutation observer already picks up.
