Fix multiscale resolution selection picking wrong scale level#591
Conversation
The heuristic in `_multiscale_to_spatial_image` used `min()` on indices from an ascending-sorted scale list, which selected *lower* resolution when x and y optimal pixel counts disagreed. It also relied on `searchsorted` over y_dims that may not be sorted after x-based reordering. Replace with a direct loop that finds the lowest-resolution scale where both x and y dimensions meet the target pixel count, falling back to the highest available resolution.
