fix: use global vars for Prometheus metrics registration in middleware

Move Prometheus metric registrations to package-level vars in both
http_middleware.go and worker_middleware.go, consistent with the
pattern used in service.go. Prevents duplicate registration panic
when multiple storage types invoke the same middleware.

Fixes #200

standalone: don't print secrets by default

By default, the standalone proxy prints all configured credentials on
startup, including the secret access keys.
This can be considered a security issue, depending on the environment
where the service is running.

With this commit, the standalone proxy avoids printing the secret keys
unless printing of secrets is explicitly requested in the config.
