Add Local Run Support and Improve Report Generation Behaviour

[riceve-fdj]

This pull request introduces several enhancements to improve local development workflows and test-report handling:

Key Changes

• Local run support:

  • Added support for passing a --test-runner-app-port argument.
  • Enabled optional automatic startup of kubectl proxy when running in a local environment.

• Report generation improvements:

  • Reports are now always saved locally, regardless of configuration.
  • Reports are only pushed to a Git repository when a git repository is explicitly configured.
  • Improved component lookup logic in test scenarios to avoid missing-component errors.

Motivation

These changes make the toolkit easier to run locally, simplify debugging, and reduce unexpected behaviour when report publishing isn’t configured.

Additional Notes

No breaking changes are introduced, and all new behaviour is fully backwards compatible.
