fix(IconForge): point the texture path at the real dump directory

Browse source 
render.py was lifted from the scratch pipeline with its default TEXDIR still
aimed at tools/IconExtract's build output — a tool that is not in the repo.
forge.py overrides the value, so the icons built correctly and the staleness
was invisible; anyone importing render.py directly would have been sent to a
path that never existed.

Default now matches where tools/MosswartArt actually writes, and a missing
texture prints a warning instead of silently dropping out: a partial texture
set renders some parts flat grey, which reads as a lighting bug rather than a
missing extraction step.

Both icons still reproduce byte-for-byte.
