feat(web-release): enhance release metadata handling and testing

- Updated `release_metadata` function to support manual testing from the main branch without publishing.
- Added tests to verify behavior for manual main runs, tag releases, and restrictions on other branches.
- Modified workflow to conditionally publish images based on the event type and added logging for manual test results.
- Enhanced documentation to clarify manual testing procedures and workflow behavior.
