fix FastSchematicReaderV3 throwing / by 0 for 1-wide/long schematics

[ZECHEESELORD]

Overview

Fixes #3359

Description

Ensure FastSchematicReaderV3 passes an immutable dimensions vector to the clipboard factory so the default pipeline can’t mutate the reader’s state and zero out 1xNx1 schematics, preventing a / by 0 when applying biome data.

interesting, that there was no report of missing clipboard data or arithmetic exceptions yet

Yeah, It's an odd edge case that only really blows up when the schematic actually carries biome data

Ah, I see - doesn't really happen with linear palettes for block data.
