feat(crew): clearer, consistent crew-creation form

- Coordinator block: shorter copy, a Remove (✕) button, and an honest
  "pointer only — real Cordn MLS isn't wired yet" note (the old paragraph was a
  wall of jargon).
- Save now blocks on a non-empty but unparseable coordinator (was silently
  dropped) instead of publishing a crew with no coordinator.
- One consistent block order for create (wizard "Extras") and edit, grouped:
  core -> squad/places -> identity (NIP-05, links, band) -> agent -> showcase
  (video, sponsor) -> treasury -> integrations (Lab link, coordinator).
