fix(T3): copy + entry points + recommender alias

Batch of small fixes from the post-audit plan:

F11 — "Mark as won" dialog copy
  Was: "This will move the interest to Completed and stamp the outcome."
  Completed was retired in the 7-stage refactor; copy now reads
  "marks Won; stage stays where it is" with a parallel Lost variant.

F13 — Bulk-add berths wizard had no UI entry point
  Page existed at /[portSlug]/admin/berths/bulk-add but nothing linked
  to it. Added a "Bulk add" button on the Berths list toolbar, gated
  on `berths.import`. Also fixed the API route's permission key
  (was `berths.create`, a phantom — switched to `berths.import` to
  match seed-permissions).

F14 — Audit Log nav entry
  Sidebar Admin section now lists "Audit Log" → /admin/audit, gated
  by the adminRequired group rule.

F18 — Recommender `limit` param ignored
  POST /interests/[id]/recommend-berths now accepts `limit` as an
  alias for `topN`. Audit sent `{limit:3}` and silently got 8 rows
  back; both names now resolve.

Tests still green.
