After the security hardening that introduced bootstrap token protection,
the first-run setup flow was broken because FirstRunSetup.tsx didn't
prompt users for the token. This caused a 401 "Bootstrap setup token
required" error during initial admin account creation.
Changes:
- Add dedicated unlock screen before the setup wizard
- Display instructions for retrieving token from host
- Include bootstrap token in quick-setup API request headers and body
- Only require unlock for first-run setup (skip in force mode)
The unlock screen follows the documented flow in README.md and ensures
only users with host access can configure an unconfigured instance.
