feat: enable integration tests on pull requests

- Add pull_request triggers to crowdsec and rate-limit integration workflows
- Integration tests now run immediately on PR push (not waiting for docker-build)
- Completes PR-based trigger support for all integration test suites
- Matches branch configuration: main, development, feature/**, hotfix/**
