#5261 added a captcha check to POST /auth/oauth/pending/create-account, but
the shared create-account form only gates its send-code button on the
Turnstile token — the submit button's disabled condition never included it.
Turnstile tokens are single-use, so handleSendCode resets the widget in its
finally block and clears the token. Submitting inside the window before the
widget re-solves omits turnstile_token from the payload, and the backend
answers ErrTurnstileVerificationFailed (turnstile_service.go:65). With an
interaction-required challenge the widget does not re-solve on its own, so
the failure persists until the user notices and verifies again — while the
button stays enabled and says nothing.
Gate the submit button on the token, mirroring the send-code button and
EmailVerifyView, which already gates its pending-OAuth submit the same way.
handleSubmit repeats the check because implicit form submission (Enter in a
text input) bypasses the button's disabled state.
The Tencent path is unaffected: handleSubmit already acquires a fresh proof
per submit, and turnstile_enabled is false in that configuration.
Verified with the component spec (11 passed) and vue-tsc --noEmit (clean).
