vite-plugin-mkcert forces the dev server onto HTTPS, but Playwright was
checking http://localhost:5173. The health check never got a response,
causing all E2E shards to time out after 60s.

Switch baseURL and webServer.url to https:// and add ignoreHTTPSErrors
to accept the self-signed cert.

1. vite-plugin-mkcert forces HTTPS; update Playwright to use
   https://localhost:5173 with ignoreHTTPSErrors.

2. In CI, set VITE_E2E=true so the wagmi config uses the accounts SDK
   webAuthn connector (compatible with virtual authenticators) instead
   of tempoWallet (iframe dialog that blocks the page). Production
   continues to use tempoWallet.

3. Update E2E tests to click 'Sign in' (matching current Login UI).

The accounts/wagmi webAuthn connector expects { method: 'register', name }
instead of { type: 'sign-up', label } used by wagmi/tempo webAuthn.
