Fix Load File: separate Auto globals; fix team/FFA double-press

Issue 1 — double press to fix team/FFA display:
  cur_team_val is updated by ConLobbyMission's -9998 signal which was async.
  Fix: call SetNetworkMissionParamater(team_allowed, ...) directly in ConLobby
  before the slot loop, then re-read cur_team_val via CTCL_GetTeamParams.
  This is synchronous so the slot display is correct on the first click.
  New file keys: TeamAllowed=0/1, TeamCount=2 (default 2 teams).

Issue 2 — Default button broken after Load File click:
  CTCL_LoadAutoFile was overwriting g_nRookieGameType/g_szRookieMission etc.
  so the Default button loaded the last auto-file params instead of defaults.
  Fix: 14 new dedicated g_nAutoXxx/g_szAutoMission globals. CTCL_LoadAutoFile
  populates ONLY these. Rookie Mission globals are never touched.
  New MAIL_LOAD_AUTO_MISSION (-6666) sent to ConLobbyMission applies the Auto
  globals (mirrors MAIL_SET_ROOKIE_MISSION_PARAMS but uses g_nAutoXxx).
  ConLobby reads game type/mission from Auto globals directly into the
  ConLobbyMission dropdowns (@ConLobbyMission@o_game_options[N].nselected).

Files changed:
  MW4Shell.cpp: 16 new globals, StartUp/ShutDown registration, CTCL_LoadAutoFile
  ConLobby.script: MAIL_LOAD_AUTO_MISSION define, updated handler
  ConLobbyMission.script: MAIL_LOAD_AUTO_MISSION define + handler
  autoconfig-file-spec.html: document TeamAllowed + TeamCount fields
Rebuild required: MW4.exe (Release + Profile).
