feat: redesign mobile Config Profiles detail, preview, and edit pages

- Rewrite ConfigProfilesMobileView to match desktop functionality:
  full detail view with all fields, preview action showing resolved
  profile, and edit view with project/tool selects, includes,
  environment variables, runtime hints, files, mounts with nested
  files, and git mounts.
- Update useConfigProfiles.handleSubmit to return boolean success.
- Update ConfigProfilesPage to pass required state and callbacks.
- Add mobile-specific CSS for config profile forms, includes,
  mount/file cards, and preview panels.
- Allow MobileDetailView to render extra children.

Quality gates: npm run typecheck, npm run lint, npm test -- --run (87 passed)
