CRITICAL: Passkey authentication was hardcoded to always grant admin role,
completely bypassing RBAC and allowing any passkey user to gain full admin access.
Changes:
- Store username and role in passkey credential during registration
- Retrieve and use stored role during authentication (not hardcoded admin)
- Fallback to admin for legacy credentials without role field
Security Impact:
- Prevents privilege escalation via passkey authentication
- Enforces proper RBAC for passkey users
- Maintains backward compatibility with existing passkeys
Tests: 214 passing
