feat(berths): website auto-promote toggle + manual-override soft-pin priority

- website_berth_autopromote_enabled (default OFF): a website registration for a
  specific, currently-available berth auto-creates a prospect (client + optional
  yacht + interest) and links the berth is_specific_interest=true, flipping the
  public map to Under Offer; general/residence/contact submissions stay
  capture-only. Marks the submission converted so a rep never double-creates it.
- derivePublicStatus now honours a manual pin (soft pin): a manually-set status
  wins over the interest-derived Under Offer, but a real permanent tenancy or an
  explicit sold still override it.
- berth rules engine respects a manual pin EXCEPT for sale triggers (-> sold),
  so a confirmed sale still wins but soft auto-changes never stomp a pin.
- Reset-to-automatic action (service + API POST /berths/[id]/status/reset + UI)
  to drop a manual pin; lock badge on every manual override (list + detail);
  divergence banner prompting reset when a pinned-Available berth has a deal.
- migration stage map updated to the §4b signed-off mapping: GQI -> enquiry
  unless it named a berth/size marker (-> qualified); SQI -> qualified.

+migration GQI marker rule. 1582 unit/integration green; tsc clean.
