nginx serves /crops/, not /images/

The site's crop store was renamed — see its own commit for why the name was wrong. This is the fourth
place that had to move with it: the constant, the development route, the build's copy target, and this
cache rule.

The rule itself is unchanged. A year and immutable is still EARNED here rather than assumed: the
filename is a hash of the original, its stamp, the framing, the slot and the width, so the bytes at a
given URL can never legitimately change.

A site published before the rename carries /images/ in its HTML and no longer has the files behind it.
The fix is a publish, which rewrites every one of those URLs anyway.
