fix(live-tv): migrate the live navigation helpers to the per-surface sidebar API

master (#1554) added `XtreamLiveChannelNavigationService` and
`stalker-live-navigation.ts`, which expand the rail through
`sidebar.setState('expanded')` on the pre-split signature. Point them at the
`portal` surface and update their specs; drop the now-unused hidden-state
stub from the Xtream layout spec, which master pushed to the max-lines
budget.
