Gitea #6: secondary MFD Damage/Critical/Heat cycling -- reconstruct the

Browse Source 
NotifyOfDisplayModeChange override (vtbl+0x4C @4d1ae4) + wire desktop 'N'

The secondary screen's schematic selector was mislabeled: @004d1ae4 (the
bits-18..20 ModeSecondary* mask swap) was reconstructed as a non-virtual
"SetControlMode" that nothing called, so the desktop stayed pinned on the
Damage view.  The binary's L4 vtable @0051e440 pins the truth:

  +0x48 = @004d1acc  <- CycleControlModeMessageHandler (FUN_004afbe0):
          forwards to the base RET no-op @004b048c.  A BAS/MID/ADV
          control-mode change never touches the secondary view
          (empirically confirmed: BT_MODECYCLE_TEST cycles the CONTROL
          MODE lamp, mask bits 18-20 unchanged, schematic stays ARMOR).
  +0x4C = @004d1ae4  <- CycleDisplayModeMessageHandler (FUN_004afcac):
          THE Damage/Critical/Heat selector, indexed by displayMode
          (table @0051dbe4 = ModeSecondaryDamage/Critical/Heat).

Authentic pod inputs (streamed type-6 .CTL EventMappings, dumped via the
new BT_CTRLMAP_LOG EVENT records): secondary-panel button 0x15 -> msg
0x15 CycleDisplayMode (manual p13, the "'Mech status Info center" bottom
left of the secondary screen), button 0x18 -> msg 0x14 CycleControlMode
(manual p6, top right), 0x10/0x11 -> ZoomIn/Out.  The DOS keyboard
fallbacks (Keypress 0x13d/0x13e = extended F3/F4) are dead under the
WinTesla VK map, hence the desktop pin.

Port wiring (the M/ModeCycle pattern): key N / pad RightThumb -> action
DisplayCycle -> gBTDisplayCycle -> CycleDisplayModeNow() -- the same body
the pod console button message drives.  Both .MAP profiles + the
compiled-in default updated.

Verified live (docked gauges + BT_SHOT, BT_VIEWCYCLE_TEST): the sec
panel cycles ARMOR DAMAGE silhouette -> CRITICAL DAMAGE subsystem list
-> HEAT DAMAGE colored list, mask 0x450421 -> 0x490421 -> 0x510421; M
control-mode cycling un-regressed (BAS/MID/ADV lamp cycles, view pinned).

Diags: BT_MODE_LOG, BT_VIEWCYCLE_TEST=<frame>, BT_MODECYCLE_TEST=<frame>,
BT_CTRLMAP_LOG now dumps EVENT records.  KB: gauges-hud secondary-view
section rewritten, CLASSMAP +0x48/+0x4C slots, decomp-reference env
gates, GAUGE_COMPOSITE phase-4 entry resolved.
