feat: extend the preset list down to 0.15 MP

The floor sat at 0.25 MP, so 16:9's cheapest entry was 768x432 — and that
one is K2-only (432 % 32 = 16), leaving 1024x576 as the smallest H3-legal
16:9 in the list. An audio-only H3 render wants 512x288, the n=1 lattice
point at alignment 32, where the video canvas is pure overhead.

Dropping PRESET_MIN_MP alone re-picks the geometric thinning and silently
drops labels — 3:2 1152x768 and 1920x1280 among them — which breaks saved
workflows, since the label string is what a graph stores. Raising
PRESET_MAX_ENTRIES to 11 in the same step absorbs that: 79 -> 87 entries
with every existing label still present and still pointing at the same
size. The six entries beyond 512x288 / 288x512 are lattice points the old
9-entry cap had been skipping over.

 Why a list and not a number: with `exact_ratio` on, the valid outputs *are* a discrete
 lattice. A continuous megapixel input advertises precision that does not exist, and
