D160: env-gated diagnostics for the Dam level-end cutscene (GE_D160)

Dam exit should play a scripted cutscene (Bond off the dam / bungee) before
the MISSION COMPLETE report; on PC it cuts straight to the report while
progression still works (bossReturnTitleStage fires). Add GE_D160=1 trace
points to localise whether the cutscene AI runs:
 - bossReturnTitleStage entry (+ caller return addr)
 - bondviewSetCameraMode (mode, stage, g_IntroSwirl, intro anim idx, caller)
 - AI EndLevel/exit_level, CameraLookAtBondFromPad, CameraSwitch (tag lookup
   result: cdef ptr / TagIndex<0 / tag NOT FOUND)
No behaviour change (all #ifdef PORT, getenv-gated).
