Build passkey add wizard UI

Add a new AddPasskeyWizard component and wire it into SecurityPage.
- Introduced AddPasskeyWizard.tsx to guide users through naming, registering, and confirming a passkey with a simulated flow.
- Integrated wizard into SecurityPage: removed inline placeholder and wired AddPasskeyWizard with stateful open/close handling.
- Replaced previous inline UI to use the new wizard for adding passkeys.
