#118: the flash overlay lands in the REAL compositor (L4VB16) + [ckflash] probe

Browse Source 
The first visibility fix painted L4GLASSWIN -- a window the operator's
single-window layout never shows. The main-window cockpit compositor is
BTDrawCockpitPanels (L4VB16): same under-the-surface masking, so the RIO
flash was again invisible. The 3b overlay now re-draws flashing lamps
(state & 3) above the surfaces there, tick-phased; [ckflash] (BT_LAMP_LOG)
logs each animated draw. Verified in-engine: addr 0x27 state 0x37
alternating shade 1 -> 3.
