25. Create wallet — passkey register → factory deploy

[Miracle656]

Goal: Implement the core account-creation flow that turns a device biometric into a
usable smart wallet. It runs WebAuthn credential creation, extracts the P-256 public key,
and deploys the wallet contract through the factory, ending with an active session on the
dashboard.
Create: frontend/mobile/app/(onboarding)/create.tsx.
Port/reference: web create path in app/page.tsx; SDK useInvisibleWallet register().
Acceptance: WebAuthn credential created → wallet contract deployed → session set → lands on dashboard.

Hi @popdadyrisky — flagging this before you put more time into it.

Auditing the open issues against the code, this one looks already implemented on main: frontend/mobile/app/create-wallet.tsx already runs the full passkey-register to factory-deploy flow. It has been exercised on mainnet — deploy tx acbc3147c89cb1ccca486ff80b8293d0c1d3d2c306600c27c52c2b64aa0f57fe.

I'm not closing it over your head, and I might be wrong about the scope. What I verified is that the code exists and is wired up — I did not check it line by line against every acceptance criterion in this issue. So:

• If what's on main covers what this issue asked for, say so and I'll close it out.
• If something here is genuinely still missing or wrong, tell me what and I'll narrow the issue down to exactly that, so the remaining work is clear and creditable.

Either way, apologies for the wasted cycles — this should have been closed when the work landed, and that's on the maintainer side, not yours.
