Add action runner management API endpoints

Implements comprehensive API endpoints for managing action workflow runs:

- POST /api/v1/repos/{owner}/{repo}/actions/runs/{run}/rerun
  Rerun a workflow run and all its jobs
- POST /api/v1/repos/{owner}/{repo}/actions/runs/{run}/cancel
  Cancel a workflow run and all running jobs
- POST /api/v1/repos/{owner}/{repo}/actions/runs/{run}/approve
  Approve a workflow run requiring approval
- POST /api/v1/repos/{owner}/{repo}/actions/runs/{run}/jobs/{job_id}/rerun
  Rerun a specific job and its dependent jobs
- GET /api/v1/repos/{owner}/{repo}/actions/runs/{run}/logs
  Download workflow run logs as archive
- GET /api/v1/repos/{owner}/{repo}/actions/runs/{run}/jobs/{job_id}/logs
  Download specific job logs
- POST /api/v1/repos/{owner}/{repo}/actions/runs/{run}/logs
  Stream workflow run logs with cursor support for real-time viewing

Features:
- Leverages existing web UI business logic for consistency
- Proper permission checking (requires repo write access)
- Support for "latest" run parameter
- Dependency-aware job rerunning using existing service logic
- Comprehensive error handling and validation
- Real-time log streaming with cursor-based pagination
- Full integration test coverage

This enables CLI tools to provide equivalent functionality to GitHub's
'gh run' command for Gitea instances.
