feat(crew): tidy the create-crew "Extras" step into collapsible groups

The Extras step stacked 9 ungrouped blocks. Now:
- Identity (NIP-05, links) — open by default.
- Sasquatch AI — open when the agent is on.
- Showcase (video, sponsor, band).
- Payments & treasury (treasury + the CLINK tip jar, moved out of "Links").
- Integrations (Lab link).
- Advanced (Coordinator) — collapsed + last, so a new founder isn't asked
  about experimental plumbing.

Other fixes:
- The crew AI agent is now labelled "Sasquatch · Pro" (it runs on the same
  Pro-gated Sasquatch proxy, falling back to a free model), with an honest note.
- crew founded year is clamped to 1954..current on save and bounded in the input.
- "Skip to end" is no longer hidden on mobile.
- Removed the coordinator copy keys left unused by the previous pass.
