Simple auth to replace transmission-daemon

[Tsai002]

Currently, rqbit lacks built-in support for simple authentication, making it challenging to secure access to the daemon without relying on external tools or reverse proxies. Adding a straightforward username and password authentication mechanism would greatly enhance the usability and security of rqbit for users who need basic access control.

greatly enhance the usability and security

This might be a bit of an overstatement, at least without TLS :) But agree there is some value in it. Do you propose to wrap the whole API into basic auth, or leave ability to do read-only calls without authentication?

[Tsai002]

The whole API is good for me.

@Tsai002 can you check if #279 is good enough

@ikatson Thank you so much. Everything works well!
