docs: end-of-sprint refresh — known issues, roadmap progress

- KNOWN-ISSUES: log 4 items surfaced during RC-Premium-01 (payment modal
  still custom, cart confirm() has no dialog pattern, stars/legacy hex
  with no token match, category/search hand-rolled skeletons), not
  previously tracked outside STORE_FRONT_UX_REVIEW.md.
- FRONTEND-ROADMAP: add Sprint 30 status (verify pass re-run green,
  git push still pending explicit go-ahead), dedupe open-items list
  against KNOWN-ISSUES.
- graphify graph regenerated (graphify-out/, cache only, not tracked).
- Obsidian notes: skipped, no running Obsidian instance in this session.
- No architecture change this sprint — no ADR links to update.
- No application code touched.
