chore(cleanup): delete nine dead components, orphaned i18n keys and unused deps

Removes verified-dead components (0 class/selector references outside
their own files): EpgListComponent (+ epg-list-item), EpgViewComponent,
LiveEpgPanelComponent, StalkerCollectionChannelsListComponent,
NavigationComponent, FilterSortMenuComponent, video-player
ToolbarComponent, PortalCollectionShellComponent and
LoadingOverlayComponent, together with their barrel exports.

Alive code extracted from the deleted trees:
- LiveEpgPanelSummary -> libs/ui/shared-portals/src/lib/live-epg-panel-summary.ts
- EpgProgramActivationEvent -> libs/ui/epg/src/lib/epg-program-activation-event.ts
- epg-list.utils.ts trimmed to the three timeline-used helpers and moved
  to libs/ui/epg/src/lib/epg-program.utils.ts
- epg-item-description/ moved up out of the deleted epg-list/ folder

Also removes 18 i18n keys now unused (from all 18 locales), dead CSS
selectors targeting the deleted elements, and unused dependencies:
lodash (+ @types/lodash), semver, @ngrx/component-store and
@videojs/http-streaming (videojs-quality-selector-hls declares no peer
dependency on it; video.js 8 bundles VHS).
