fix: Remove mixed uses/run keys and duplicated steps in deploy-dev.yml

- Fixed 'Run smoke test' step that had both 'uses' and 'run' keys
- Removed all duplicated deployment sections and jobs
- Added service manifest application before patching
- Simplified workflow to focus on core deployment functionality
- Removed duplicated kubectl setup and Playwright testing sections
- This should resolve the GitHub Actions validation errors for dev deployment
