fix: use static Tailwind classes for responsive hide_on breakpoints
Replace dynamic string interpolation in table component's hide_on and
action_hide_on with a helper that returns complete static class strings.
Tailwind's purge scanner cannot detect dynamically constructed classes
like "hidden #{breakpoint}:table-cell", causing them to be stripped from
the CSS output.
