Add support for per-department custom daily targets

- Introduced `department_daily_targets` field in criteria, renderer, and API to define daily target overrides for departments.
- Enhanced daily target logic to honor per-department overrides while maintaining backward compatibility.
- Updated SMS, email, and Slack renderers for consistent enforcement of text length limits with fallback to non-mbstring functions.
- Refactored order item update logic to improve database interaction safety by using setters.
