fix: setting Secure behind nginx 

bug was due to having explicit 'serve --http=address' when running
behind nginx on NixOS server
So either a more complicated check was required, or just setting
Secure=true unconditionally.

This seems to be a better way, because Firefox already allows secure
cookies beng sent and received from localhost for dev purposes, and
Chromium does too

** TODO maybe add middleware so that 401 would be a page, and not json
** TODO get icons for the auth providers. surely they are accessible from the pocketbase itself?
