Kristoffer Dalby 87c230d251 integration: add run ID isolation for concurrent test execution ...

Add run ID-based isolation to container naming and network setup to
enable multiple integration tests to run concurrently on the same
Docker daemon without conflicts.

Changes:
- hsic: Add run ID prefix to headscale container names and use dynamic
  port allocation for metrics endpoint (port 0 lets kernel assign)
- tsic: Add run ID prefix to tailscale container names
- dsic: Add run ID prefix to DERP container names
- scenario: Use run ID-aware test suite container name for network setup

Container naming now follows: {type}-{runIDShort}-{identifier}-{hash}
Example: ts-mdjtzx-1-74-fgdyls, hs-mdjtzx-pingallbyip-abc123

The run ID is obtained from HEADSCALE_INTEGRATION_RUN_ID environment
variable via dockertestutil.GetIntegrationRunID().
