cli: hub-era help text; don't print unused projects.json path under SQL metadata

Root --help still described the retired direct-to-bucket model (S3/GCS as
the sync transport); clients sync only through a hub now. And with
database: sqlite/postgres the hub startup line printed a projects.json
path that is never read — misleading for self-hosters checking where
their metadata lives.
