fix(auth): complete login by reading userinfo from response envelope

oauth/userinfo returns { success, data: {...} }, so after the interceptor
unwraps once the user lives at res.data, not res. getInfo checked
res.uuid (undefined), so it never set the userInfo cookie or redirected —
the /login page just sat there after entering the OTP. Read res.data,
store the user object (with a username alias for mobile_number so the
appointment flow keeps working), redirect via location.href, and show a
toast instead of silently staying when userinfo fails.
