fix(ContactShadows.vue): remove unnecessary TypeScript error suppression

- Removed the `@ts-expect-error` comments in the `blurShadow` function, as they are no longer needed. This change improves code clarity and maintains a cleaner codebase by eliminating outdated error handling comments.
- The removal aligns with ongoing efforts to enhance type safety and maintainability in the project.
