[PATCH v1 4/6] add responsive extras and footer layout adjustments to contain overflow

[Rito Rhymes <rito@ritovision.com>]

Below 848px, fixed-width extras and footer blocks overflow the page and
create page-wide horizontal scrolling that breaks layout.

Make extras and footer sections responsive by switching extras to
wrapping layout, stacking blogroll/social blocks to full width, and
relaxing fixed heights/widths. Update donors to wrap logos and hide
manual <br> breaks so the sponsor area reflows naturally on small
screens.

Add 550px and 400px refinements to progressively reduce
blogroll/social column counts (3 -> 2 -> 1), preventing overlap and
preserving readability as viewport width shrinks.

This patch is intentionally limited to extras/footer behavior; content
and homepage table overflow handling are addressed separately.
