Tutorial start message not re-shown when loading early save

[dalerank]

Summary

Loading an early mission save does not re-show the tutorial start message (Vanilla does).

Reported

When you load a mission in Vanilla that's kind of just started, it will show the tutorial message again.

Code notes

• mission_show_start_message() in missions.js skips if mission.start_message_shown is true.
• That flag is persisted in g_scenario.vars (saved with the map) and survives load.
• event_mission_start still fires on load, but the guard blocks re-display.
• Legacy iob_tutorial_flags chunk is read into discarded locals ( utorial.cpp).

Expected

Match Vanilla: early / just-started saves should show the tutorial briefing again on load (or clarify intentional modern behavior).
