wip: Improve deep link validation and error handling

- Add comprehensive route validation with zod schema
- Create type-safe DeepLinkRoute enum for all valid routes
- Add structured error handling for invalid routes
- Redirect to error page with detailed feedback
- Add better timeout handling in deeplink tests

The changes improve robustness by:
1. Validating route paths before navigation
2. Providing detailed error messages for invalid links
3. Redirecting users to dedicated error pages
4. Adding parameter validation with specific feedback
5. Improving type safety across deeplink handling
