feat: ship templates, crew fields, and read/edit dashboard

- Add crew_req, hardpoints, cargo fields (DB migration + server + types)
- Add 10 ship templates from Appendix A (Caravel, Galleon, Sloop, etc.)
- Enhanced CreateShipModal with template picker that auto-fills all stats
- Dashboard defaults to compact read-only view; Edit button toggles to
  editable steppers/dropdowns
- New CrewSection showing crew required, hardpoints, and cargo
- Two-column form layout in create modal for better use of space
- Fix .gitignore data/ pattern to only match root-level data directory
