parse 26.x texture objects in block models (redstone, glass, panes)

Since 26.x a model texture can be an object {"sprite": ..., "force_translucent": ...}
instead of a string. The block-model DTO only accepted strings, so those
models failed to load and rendered as the grey fallback cube: redstone
wire and every glass block and pane (110 models). Accept both forms in
ModelResolver (shared with ItemGeometry).
