Sebastian Krüger f2d2bd7e25 chore: streamline Docker workflow with attestation support
Updated GitHub Actions workflow based on kit.pivoine.art template:

Permissions:
- Added id-token: write (required for attestations)
- Added attestations: write (enables build provenance)

Improvements:
- Added workflow_dispatch trigger for manual runs
- Updated docker/build-push-action from v5 to v6
- Added conditional login (skip on pull requests)
- Added artifact attestation step with actions/attest-build-provenance@v2
- Generates and pushes build provenance to registry
- Provides supply chain security and transparency

Attestation benefits:
- Verifiable build provenance
- SLSA (Supply chain Levels for Software Artifacts) compliance
- Cryptographically signed metadata about build process
- Helps users verify image authenticity

The workflow now matches modern Docker image publishing best practices
with full attestation support for enhanced security.
