feat(settings): enhance getUpdateData and reloadDockerResource for image digest comparison

- Added logic to getUpdateData to compare current and latest image digests for canary and feature tags, indicating if an update is available.
- Updated reloadDockerResource to ensure the correct image tag is used during dokploy service updates based on the current image tag.
