Remove dead code across plugin: unused members, constants, includes

- EL_LOG() function + JsonUtilities.h include (WebSocketProxy)
- SilenceBuffer, bSpeculativeTurn (ElevenLabsComponent + proxy)
- bSignedURLMode, SignedURLEndpoint (plugin settings)
- bHasPendingAnalysis (LipSyncComponent)
- bForceSelectionActive (InteractionComponent)
- UserActivity, InternalTentativeAgent constants (Definitions)
- Engine/AssetManager.h includes (EmotionPoseMap, LipSyncPoseMap)
