feat: add standalong dataplanes for K8S

[paullatzelsperger]

What this PR changes/adds

Adds a standalone dataplane runtime for the Kubernetes deployment. Also cleans up the deployment a bit and adds:

• proper kubernetes probes (readiness, startup, liveness)
• defensive seeding of the super-user (skips if already exists)
• clean-up of some deprecated modules in libs.versions.toml
• bumps to EDC 0.8.0

Why it does that

no data can be transferred without data planes

Further notes

• removed the CodeQL job, as it takes very long, and this is only a sample project anyway

these todo's will come in subsequent PRs:

• still missing: adding HTTP assets to the provider connectors that can be transferred
• update the IntelliJ deployment to also contain dataplanes, probably with embedded dataplanes
