Closes https://github.com/go-gitea/gitea/issues/39287
Security key nicknames could only be set at registration, so a skipped
nickname left an auto-generated hex name until the key was
re-registered. Each key now has a Rename button opening a dialog with
the current nickname. A nickname used by another of the user's keys
(case-insensitive) or a blank nickname is rejected. Renames are recorded
as `user:webauth:rename` audit events.

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.
