Plan item C6 step 3 for libs/portal: the nine Eager components in
portal/shared/ui, portal/stalker/feature and portal/xtream/feature switch
to OnPush. Their templates read signals, signal inputs, async pipes and
template-event state; the plain fields they write outside events
(playback request ids, save throttles) are not rendered.
The already-OnPush live channel lists filled their favorites Maps in a
subscription and the Xtream list dropped programme previews after the EPG
mapping dialog, all without marking the view. They now call markForCheck
like the neighbouring handlers do, so a late favorites answer shows its
hearts without waiting for an unrelated check. A regression test for the
Xtream list fails without the call.
