feat(D.2b): main-pack cell draws the constant backpack icon (AP-51)

Browse source 
The m_topContainer cell (0x100001C9) rendered blank (tex=0). Retail's
IconData::RenderIcons (0x0058d1ee) has an IsThePlayer() branch that draws a
CONSTANT backpack — m_idIcon = GetDIDByEnum(0x10000004, 7) = 0x060011F4,
m_itemType = TYPE_CONTAINER — NOT the player's body icon (the original AP-51
"equipped-pack weenie icon" premise was wrong). Compose that base over the
Container type-underlay via the existing _iconIds delegate. Verified vs decomp
(407546-407549) + IconComposer.GetIcon (base=arg2, type drives underlay) + a
live dat dump (map 0x25000008 index 7 = 0x060011F4). Test locks type+literal.
AP-51 reworded to the residual hardcoded-vs-runtime-resolve nuance (cf. AP-55).
