refactor(search): improve SQL search handling and optimize project list component

- Enhanced search handling in WorklenzControllerBase to properly escape single quotes, preventing SQL syntax errors.
- Refactored search logic in ProjectList to maintain reference stability and improve performance during debounced searches.
- Removed unnecessary console logs and optimized loading state management for better user experience.
