Fix Play button: unload sublevel + use full map path for OpenLevel

Browse Source 
OpenLevel("test") was resolving to the streamed sublevel instance
(test_LevelInstance_5) instead of the actual map. Fix:
- Unload sublevel via LoadBaseLevelAsSublevel("None") before OpenLevel
- Use full path "/Game/{BaseLevel}" to avoid ambiguity

Also: all widget lambdas now get SpawnManager/SceneSerializer fresh from
PlayerController (critical fix for packaged builds where weak ptrs are null).
