[pbs-devel] [PATCH proxmox-backup 1/1] ui: login: opt the tfa challenge handling into the new HttpOnly flow

[Shannon Sterz]

this was missed previously leading to the tfa part of the auth flow
not opting into the new auth flow. this meant the server did not add a
Set-Cookie header. after that whether or not a login worked fine
became a race between the refresh logic (which was opted into the new
flow and, thus, would yield a proper HttpOnly cookie) and other
requests.

Applied, thanks!

tiny nit: we would prefer camelCase in JS, but that's just internal so we can
change it at any time with a fallback to the previous property.
