design the `login` page

[monsieurbadia]

hello 👋 I tried to follow the design of the website: https://glslsandbox.com. That is to say, to respect the current graphic chart and try to adapt it for a login page. You are free to make any changes you want. Let me know if I have forgotten anything important 👽

Hmm, that login is only for the admin though. It's not really user facing...

Definitely no need for "forgot password?" 🤓

I wasn't sure. You're right, we don't need the "forgot password?". I just removed it.

Thanks!
