feat(request): don't make filter and page parameters optional by default

This allows to define defaults within the Zod schema for filter and page instead
of having to resolve it within the middleware.

BREAKING CHANGE: when filter or page is defined, it is now required by default.
To get the old behavior, add `.optional()` to your schemas.
