fix(pagination): add sr-only span to preserve aria-current on mobile AT

When the mobile label is aria-hidden and the desktop button container is
display:none (below sm:), mobile screen reader users had no aria-current
indicator. Added a sr-only span with aria-current="page" that stays in
the AT tree at all breakpoints regardless of CSS display state.

On desktop the active page button also carries aria-current — both
announce the same page information, which is acceptable.
