fix: improve TypeScript type safety across views

Changes:
- Add proper type annotations for component properties
- Fix null checks with optional chaining
- Add missing interface properties
- Replace any with proper types where possible
- Move interfaces from endorserServer to interfaces/
- Add proper Router and Route typing
- Add default empty string for optional text fields

This improves type safety and reduces TypeScript errors across views.
