Message:

auth: all Google login errors as clear explanation blocks (codes instead of bare alert)

The Google callback now redirects with ?gerr=<code> (admin/session/email/linked/
unavailable/failed) and auth-login.ejs maps each code to a clear explanation block
with icon + heading + text (admin gets the two login paths as well). Completes the
error indication consistently; free-form ?error= text remains as fallback for the
regular alert.
