Add Actions API endpoints for workflow run and job management

Implements comprehensive REST API endpoints for GitHub Actions workflow runs:

- POST /actions/runs/{run}/rerun - Rerun entire workflow run
- POST /actions/runs/{run}/cancel - Cancel running workflow
- POST /actions/runs/{run}/approve - Approve workflow requiring approval
- POST /actions/runs/{run}/jobs/{job_id}/rerun - Rerun specific job
- GET /actions/runs/{run}/logs - Download run logs archive
- GET /actions/runs/{run}/jobs/{job_id}/logs - Download job logs
- POST /actions/runs/{run}/logs - Stream logs with cursor support

Features:
- Proper permission checks and workflow validation
- Support for "latest" run parameter
- Job dependency handling for reruns
- Streaming log API with cursor-based pagination
- Comprehensive test coverage

Fixes workflow management gaps in API compatibility.
