fix(D.2b): chat input resolves the live command bus lazily (was bound to null) + register thumb-3-slice row

Browse source 
The live session + its LiveCommandBus are created after the retail-UI block in
OnLoad, so binding the bus by value captured NullCommandBus and silently dropped
outbound chat. Pass a Func<ICommandBus> resolved at submit time (mirrors how the
ImGui ChatPanel re-reads the bus each frame).

AP-41: scrollbar thumb drawn as single stretched tile (0x06004C63) instead of
retail's 3-slice top-cap/middle/bottom-cap — acknowledged in UiChatScrollbar.cs:37,
registered per the divergence-register rule.
