chore(sample): remove experiment mode UI from the sample app
The Experiment Mode menu toggle and the bottom-center Start/Stop
overlay were dev tooling, noise for anyone poking at the sample app.
Drop both.
The underlying ExperimentLogger, ExperimentEvent, the two capture
LaunchedEffects, and the intent-driven auto-mode path all stay — so
orchestrator-driven comparison runs (MainActivity test_mode extras)
continue to work without any UI visible.
