A large scale (e.g. 200x on a thin column) made the warp fill every tile of
a result up to 2^21 px on a side, enough to exhaust memory. Free Transform
now prices each warp before building anything and refuses with an
allocation-style error ("...; the document was not changed") once a result
would exceed MAX_TRANSFORM_PIXELS (2^30, the same bound as Puppet Warp's
MAX_WARP_PIXELS). Only the result's size counts, so moving content far off
the canvas still works, and nothing is clipped.
The check covers the layer, a smart object's cache and filter mask, linked
masks, a lone mask/channel target and the selection outline, and runs over
the whole layer tree before any layer is changed. Transform Selection gets
the same check. The transform box now stays open when a commit is refused.

* Make large pixel operations allocation-fallible
* Warp: drop the fixed 400 MP cap; fallible reservations already cover large transforms

* Adapt #2530 to main: fallible steep-Distort warp, Result from mask paste in float moves; regenerate scorecard
