Yeah, but then the server must know the plaintext password to check the client reply, which is exactly the problem password hashing schemes were designed to solve.

That issue is solved by simply having "hash(password+salt)" the thing the server has stored and is checking.
In other words you can combine salts + hashes + nonces to both eliminate the server's need to know the password and the possibility of a replay attack.
