Bcrypt password hasher for migration from bcrypt to Argon2id.
This module implements the Sigra.Hasher behaviour using bcrypt_elixir.
It is intended for transparent hash migration: when a user logs in with
a bcrypt-hashed password, it is verified and then re-hashed with Argon2id.
bcrypt_elixir is an optional dependency. If it is not loaded, calling
hash_password/1 or verify_password/2 will raise a descriptive error.
The no_user_verify/0 function gracefully falls back to Argon2 timing
when bcrypt is unavailable.
