chore(coverage): move shared-portals to Tier C, fix stale doc references

The Tier A gate failed in CI because deleting the dead epg-view and
live-epg-panel components removed the only specs in libs/ui/shared-portals.
The lib now contains a single type-only interface (LiveEpgPanelSummary),
so there is no runtime code to unit test; reclassify it to Tier C with a
documented reason, matching the gate's own guidance.

Also update remaining doc references to the deleted components in
docs/architecture/stalker-epg.md, iptvnator-ui-guidelines.md and
CLAUDE.md.
