fix: auto-set storage_provider to remote on claim and api_key/worker_url config

CLI defaulted to sqlite storage after claim, causing inbox to read from
an empty local database instead of the remote API. Now explicitly sets
storage_provider to "remote" in all config paths: claim, config set
api_key (for @mails.dev), and config set worker_url.
