fix: Resolve Docker Secrets in all() method for empty variables

- Update all() to automatically resolve Docker Secrets (*_FILE pattern) for empty variables
- Ensures DB_PASSWORD, REDIS_PASSWORD, etc. are resolved from their *_FILE counterparts when empty
- Variables like DB_PASSWORD_FILE are still included in output, but empty values are replaced with resolved secrets
- Fixes issue where DB_PASSWORD and REDIS_PASSWORD appeared empty in logs even though *_FILE variables existed
