fix: eliminate all @typescript-eslint/no-explicit-any warnings

- Replace any type assertions with proper type definitions
- Add null safety with fallback values for undefined fields
- Improve error handling with type-safe string assignments
- Use JSON.stringify for non-string error objects
- Maintain runtime compatibility while improving type safety

Files changed:
- src/views/DIDView.vue: Fix claim type assertions and error handling
- src/views/ContactsView.vue: Fix registration payload and catch block typing
