fix: correct set-password docstring (scrypt, not bcrypt)

The set_password_cmd docstring and inline comment claimed bcrypt /
SHA-256, but the implementation actually uses scrypt via
cryptography.hazmat.primitives.kdf.scrypt. Correct the docstring,
drop the misleading comment, and remove the now-unused hashlib import.

No behavior change.
