James Dansereau dac4ae7c0c D228: fix white NPC-weapon-texture patches -- IA16 palette intensity/alpha byte-order bug
GE_TEXDUMP on Facility (-level_34) found ~14% of LOD-textured CI uploads
whose palette is IA16 (intensity-alpha, not RGBA16) rendering solid
near-white. A GE_D228 correlation probe ruled out the texpool/RC2-clip
hypothesis this row started with -- decoded size exactly matched the base
tile every time, so the data reaches import_texture fine.

The real bug: palette_to_rgba32's G_TT_IA16 branch read
intensity = palentry & 0xff (low byte), alpha = palentry >> 8 (high byte)
-- backwards relative to the already-correct direct-IA16 decode
(import_texture_ia16) a few lines above it in the same file, which reads
intensity from the first byte (high, after gfx_dp_load_tlut's PD_BE16
swap) and alpha from the second. A dim, fully-opaque palette entry (e.g.
intensity=0x58, alpha=0xff) decoded backwards as bright and
mostly-transparent -- the white-patch symptom.

Fix: swap the two lines to match the working convention.

User-verified live: AK47 and other metallic guns render correctly.
Headless -level_34 run crash-free pre-verification; a full sweep is
still owed (the user's own game instance was running concurrently this
session, so verify.sh/taskkill were avoided).
