Front end: post-mission results screen (kills/deaths scoreboard)

Completes the marshal chain: menu -> mission -> timed stop -> results ->
relaunch.  BT had no mission-end score flow; this builds one from the
data the Comm MFD pilotList already tracks.

- btl4console: at the timed stop (game thread, state still live) snapshot
  each roster pilot's kills/deaths via the BTResolveRosterPilot /
  BTPilotKills / BTPilotDeaths bridges; expose BTLocalConsole_ResultCount
  / GetResult.
- btl4fe: BTFrontEnd_ShowResults -- a GDI green-on-black 'MISSION COMPLETE'
  scoreboard (PILOT / KILLS / DEATHS, slot 0 named from the menu), any
  key or ~12s to dismiss; store the last pilot name.
- btl4main: show the scoreboard after a marshaled mission, before the
  relaunch.

Verified: MISSION COMPLETE screen renders with the pilot row and the
snapshotted score (0/0 on a no-combat test run; the data path is the
same one the live Comm MFD reads).

Phase 5 (front end) COMPLETE: menu + egg builder + marshal + timed stop
+ results + single-binary (relaunch) loop.
