qa wip: spawn in front of facade + input/sim diagnostics

- PlayerStart moved to (-10722,-2400,800) clear air, facing the facade.
- Force game input mode + hide cursor at BeginPlay.
- Diagnostics: every-second world/Z/gravity/fall log; one HighResShot at 1.5s.

Verified (packaged, engine log): controller connects to pawn input=yes, ctx
pushed, actions bound, world ticks, gravity -980, but capsule stays Z=909
fall=0 forever and no input fires. Static airborne pawn + no fall + no input
= pawn simulated without an active autonomous local player. Recorded for next
debug; do not merge to main.
