feat(uat-p5): long-tail polish - tag chips, notes counts, hub context, tenancies toggle

- StageStepper renders now carry tag chips next to the progress bar
  (client interest cards, pipeline summary, preview sheet).
- Notes tab badge on the interest detail aggregates note counts across
  the interest, the linked client, the linked yacht, and any companies
  the client is an active member of - reps see the full surface area
  at a glance.
- Admin Settings: Tenancies Module toggle wired into the Feature Flags
  card. Disabling hides nav/tabs without deleting any rows; re-enabling
  brings them back. Service layer was already complete; this surfaces
  the control on the operations page.
- HubRoot recent-files rows now show folder breadcrumb + entity badge
  (Interest/Client/Yacht/Company) so reps can tell at a glance where a
  file lives. Backed by listFiles enrichment (5 batched lookups per
  page; no per-row queries).
