fix(config): Improve Consul config loading and add version info

- Fixes an issue where configuration from Consul was not being loaded correctly due to multiple base64 and encoding issues.
- Adds robust decoding logic with fallbacks to handle different value formats from Consul.
- Adds the Git commit SHA as a version identifier to the Docker image and application logs to improve debuggability.
