v0.27.3:0 - cap image resolution (fix oversized-image 400); remove vision-check button

A 12MP photo expands past vLLM's ~4096-image-token limit -> 400. Cap via
--mm-processor-kwargs max_pixels in the qwen36 recipe so big images auto-
downscale server-side for every /v1 consumer (verified live: 400->200).
Remove the v0.27.2 in-dashboard vision-check button per owner request; the
vision badge already signals capability.
