feat: enhance navigation validation by integrating validation checks

[walldenfilippa]

…in navigation components

Description

Returns a function that synchronously checks whether navigation from the current page to a given target page is visually prevented. Navigation is prevented if any page strictly between the current and target page has a validationOnNavigation config AND has actual errors that match that config's mask. This mirrors the check done asynchronously in click handlers, but uses already-computed validation state for synchronous use in render (e.g. disabling buttons).

This is also reflected in the navigation component and the customButton component.
