Pull request overview

This PR updates Rust integration tests to use a mirrored tinyproxy container image hosted on GitHub Container Registry (GHCR), aiming to reduce CI flakiness caused by upstream registry rate limits.

Changes:

• Switch tinyproxy testcontainer image reference from registry.gitlab.com/kalaksi-containers/tinyproxy:1.7 to ghcr.io/kubewarden/tests/kalaksi-tinyproxy:1.7 in multiple test suites.
• Keep existing container startup wait condition (Starting main loop) and exposed port configuration unchanged.
