Add delete/dissolve for crews and Lab profiles via NIP-09 (v1.0.72)

- New useDeleteEntity hook: publishes a kind:5 deletion request referencing
  the target addressable event by `a` coord, `e` id, and `k` kind. Owner-only.
- New reusable DeleteEntityDialog: owner-gated trigger + confirmation with a
  clear "deletion is best-effort on decentralized relays" warning, redirect,
  and query invalidation so the item drops out of lists.
- Wired "Disband" into CrewDetailPage (founder only, redirects to /crews).
- Wired a "Manage → Delete Profile" card into CoachDetailPage for all Lab
  profile types (coach/filmer/editor/photographer/builder), redirects to /lab.
