Fix memory leaks and add debug tools, remove ControlCenterTip

Memory optimization:
- Add onDisappear cleanup for repeatForever animations in LockScreenView
- Add onDisappear cleanup for animations in FeelsSubscriptionStoreView
- Add onDisappear cleanup in AddMoodHeaderView and PaywallPreviewSettingsView

Debug improvements:
- Add test data and clear data buttons to Settings (debug builds only)

TipKit changes:
- Remove ControlCenterTip (unused)
- Add TipKit-Tips.md documentation
