hotfix(isa-app-ui/shared-searchbox): improve component initialization and method safety

Enhance searchbox component reliability by addressing initialization
issues and improving method safety across both shared and ui implementations.

Key changes:
- Fix potential null reference errors in cancel search functionality
- Improve method parameter typing with explicit defaults
- Add proper initialization for ControlValueAccessor callbacks
- Enhance component property initialization with explicit types
- Add hintCleared output event for better hint management

These changes resolve runtime errors and improve type safety
for the searchbox components used throughout the application.
