Refactor all scripts to use common.sh for consistent colored logging

- Update restore.sh to use common.sh instead of inline log function
- Update update.sh to use common.sh instead of inline log function
- Update recover.sh to use common.sh instead of inline log function
- Update check-health.sh to import colors from common.sh

Benefits:
- DRY principle: color definitions in one place
- Consistent logging across all scripts
- Easier maintenance: change log format once
- All scripts now have colored output in terminal
- Reduced code duplication (48 lines removed)
