redis, postgres and minio adapters drop generatePassword + the returned credential:
each creates the resource under the login the mesh derived (`as`) with the password
the mesh minted (`p.password`). minio's client gains a secret-key argument so it sets
the mesh's secret rather than generating one. umami (analytics) is re-pointed at the
new contract too; its siteId return is a data-provision concern ADR 0053 scopes out.
Proven: mesh-lab provider-uses-mesh-credential green — redis creates the consumer's
login with the mesh's password, the consumer authenticates (PONG), no seal key set.
