The "login" prefix makes this option more confusing rather than clearer,
because what other account types are there? LDAP ones for example, but
you can login with those too, so the prefix is pointless.
We now explain what Radicale even is and classify reusing the hashed
passwords of login accounts as limitation because it requires using
compatible password hashes.
This is difficult because compatible password hashes need an overlap
between libxcrypt and Radicales choice of libraries: libpass, argon2 and
bcrypt.
Extract the source code into a proper .nix file so we get source linting
and formatting for free. Pruned from bad practices of the past, like
global `with lib`.
