fix series share navigation and menu placement

Three problems reported on series shares. The ShareLink action landed
at the bottom of the series menu because the fallback injector cloned
the last item and appended; it now clones the first item and inserts
at the top, matching where it sits for movies. Guests could not open
season or episode pages because guest mode disabled pointer events on
all cards; cards are clickable again, since the server-verified route
check and the tag policy already control where a guest can actually
go. The injected item also inherited the template's data-id, which
could shadow a real menu command like Informations; it is stripped
now.
