debug: disable all loading ticks and end sections, add flow logging

All DDGame__LoadWeaponSprites_Maybe calls disabled (both locations).
End sections (HUD, sprite inits, GfxHandler close, display
finalization) disabled pending field comparison.

Log analysis shows constructor gets past 8 SpriteRegions + 1 arrow
sprite iteration but then hangs — likely in the second arrow or
the load_resource_list section. Need to investigate arrow loop or
sprite resource loading hanging.
