fix(footer): stretch block container to full viewport to close white gap

Browse Source 
Option 1 (tightening ``padding-bottom`` from 3rem to 2rem) did not
eliminate the gap. The remaining gap is ``.stApp``'s solid white
background showing through the area below the block container's
natural (content-sized) bottom edge — visible because the home
page's content is shorter than the viewport.

Stretch the block container with ``min-height: calc(100vh / 0.85)``
so the container itself fills the visible viewport. Now the area
between the last finding card and the fixed footer is the block
container's own background, not ``.stApp`` showing through —
visually continuous with the content above.

The ``/0.85`` compensates for ``.stApp { zoom: 0.85 }`` (defined in
``_HIDE_CHROME_CSS``): inside a zoomed container, ``100vh`` renders
at 85% of true viewport height, leaving a 15% gap if used raw.
``box-sizing: border-box`` keeps the 2rem padding part of the
total height instead of stacking onto it.
