fix: move loading ticks to correct positions, add second pair

Original constructor has 4 DDGameWrapper__LoadingProgressTick calls:
- 2 after coord_list, before load_resource_list
- 2 after DDGame__LoadHudAndWeaponSprites

Our ticks were placed before GfxResource__Create (too early). Moving
them to the correct positions enables the message pump at the right
times during construction, which processes pending sprite loads.

This should fix the weapon menu freeze (sprites weren't loaded during
construction, causing on-demand loading on first right-click).
