chore: add dynamic annotations to Dockerfile

[philprime]

• Replaced deprecated org.label-schema.* labels with OCI-standard org.opencontainers.image.* annotations in the Dockerfile
• Consolidated label declarations into a single multi-line instruction for better readability
• Added org.opencontainers.image.licenses="Apache-2.0" label to properly document licensing
• Created a hooks/build script for Docker Hub automated builds that:
  • Dynamically sets org.opencontainers.image.revision from the Git commit hash
  • Sets org.opencontainers.image.created using the current build date in RFC 3339 format
  • Uses SOURCE_BRANCH to set the org.opencontainers.image.version label

Reasoning

This PR updates our Docker image metadata to follow Open Containers Initiative (OCI) standards, which have superseded the older org.label-schema convention. The dynamic labels set through the build hook enhance traceability by recording when images were built and from which exact Git commit, improving our build audit trail and making image identification more precise.
