The Issues/PR numbered-pagination page-jump field silently clamped any
typed number to [1, totalPages] only on submit -- typing '999' would
quietly land on the last page with no explanation. The field now shows
isError/supportingText whenever the currently-typed value is out of
range, making the clamp visible before the tap. Submitting still
clamps exactly as before; this only adds visible feedback.
