fix: remove branch restriction from Docker workflow_run trigger

The Docker workflow was not triggering for tag-based releases because it had
'branches: [main]' restriction in the workflow_run configuration. When pushing
tags, the triggering workflow runs on the tag, not on main branch.

Changes:
- Remove 'branches: [main]' from workflow_run trigger
- Simplify tag detection using github.event.workflow_run context instead of API calls
- Use official workflow_run event properties (head_branch, event) for reliable detection
- Support both 'refs/tags/VERSION' and direct 'VERSION' formats
- Add better logging for debugging workflow trigger issues

This fixes the issue where Docker images were not built for tagged releases.
