Registration omitted `userVerification`, so Chromium raised the credential to credProtect level 3 and the authenticator then hid it from the second-factor login, which asked for `discouraged`. Registration and each login now set their own value, with `preferred` on the second factor so credentials already registered at level 3 keep working without re-enrollment. Also add relevant e2e test coverage for webauthn, one test chromium only because Firefox lacks the APIs needed. Fixes https://github.com/go-gitea/gitea/issues/33531 Fixes https://github.com/go-gitea/gitea/issues/36019 Fixes https://github.com/go-gitea/gitea/issues/38139
