Add dynamic apply wizard customization with admin settings UI

- Create wizard config types, utilities, and defaults (wizard-config.ts)
- Add admin apply settings page with drag-and-drop step ordering, dropdown
  option management, feature toggles, welcome message customization, and
  custom field builder with select/multiselect options editor
- Build dynamic apply wizard component with animated step transitions,
  mobile-first responsive design, and config-driven form validation
- Update step components to accept dynamic config (categories, ocean issues,
  field visibility, feature flags)
- Replace hardcoded enum validation with string-based validation for
  admin-configurable dropdown values, with safe enum casting at storage layer
- Add wizard template system (model, router, admin UI) with built-in
  MOPC Classic preset
- Add program wizard config CRUD procedures to program router
- Update application router getConfig to return wizardConfig, submit handler
  to store custom field data in metadataJson
- Add edition-based apply page, project pool page, and supporting routers
- Fix CSS (invalid sm:fixed-none), Enter key handler (skip textarea),
  safe area insets for notched phones, buildStepsArray field visibility
