[ci] Align Storybook workflows with Playwright improvements

- Add null checks for head_repository to prevent errors with forked PRs
- Simplify job status output using direct variable assignment
- Remove unnecessary workflow conclusion fetching (use event data directly)
- Improve logging for workflow trigger debugging
- Only download artifacts when workflow succeeded
- Remove duplicate start time calculation
- Align error handling with playwright workflows

These changes bring the Storybook deployment workflows in line with
the improvements made to the Playwright workflows, providing better
stability and consistency across CI/CD processes.
