Enhance CI/CD workflow and documentation

Updated `docker-image.yml` to rename the workflow, add debugging steps, and verify `HttpClientFactory` presence. Upgraded Docker actions and added metadata extraction, local testing, and Trivy security scanning. Improved cache management and output details.

Refined `Dockerfile` to use wildcard patterns for project files and optimized the publish command for smaller image size.

Created comprehensive documentation: `GITHUB_ACTIONS_FIX_SUMMARY.md` for action resolutions, `ACTIONS_FAILURES_ANALYSIS.md` for in-depth failure analysis, `ACTIONS_FIX_CHECKLIST.md` for tracking fixes, `GITHUB_ACTIONS_TROUBLESHOOTING.md` for troubleshooting guidance, and `GITHUB_CLI_REFERENCE.md` for CLI usage.

Added `check-dependabot.ps1` script to verify and guide `dependabot.yml` configuration updates.
