feat(portfolio): add design.aspect_ratio knob for card images

Card image dimensions were hardcoded: a fixed-height box (h-48) plus a fixed
3:2 crop (Fill "600x400"). The box ratio therefore tracked card width / column
count and rarely matched the crop, so object-cover re-cropped the already
cropped image (a double-crop).

Add a `design.aspect_ratio` knob (square | landscape | portrait | wide | photo)
that mirrors the gallery block's vocabulary and drives BOTH the CSS aspect box
and the Fill dimensions from one map, so the box always matches the crop — a
single, predictable crop at any width / column count.

Defaults to `photo` (3:2, 600x400), preserving the previous appearance, so it's
non-breaking. All aspect class strings are literal in the template so Tailwind's
scanner emits them. Documents the option in the block README.
