[Feat] [MUST] ADD login with permission & IP ban

[RaSan147]

Required for extreme level security

• Need to solve [Feat] [MUST] IP whitelist and blacklist #26 first

Add log in feature.
Heres how:

1. Create account by asking the admin (offline), the admin will create {"username": ["$salted password hash", permission_level]
2. Also create a list ["token"+"permission_level]

ie: "dhskdh398wjr9" , the last "9" is the permission level

because same user may use multiple PC with multiple browsers.

So the server will generate a token and store it on Cache (use https://docs.python.org/3/library/http.cookies.html and https://developer.mozilla.org/en-US/docs/Web/HTTP/Cookies) (use HttpOnly and same-origin?)

Check it with server and on every request, update the hash with new one with a Constant amount of expire days defined in the config

4. On multiple failure (define in config), put the IP on blocklist
5. Ask admin to manually remove that...

For IP ban, create a historical log for IPs used by a used a user and last access time.
