fix: preserve content when toggling panning gesture

Motivation

Changing enableContentPanningGesture currently swaps the content wrapper between BottomSheetDraggableView and Animated.View. Since those are different component types, React unmounts and remounts the entire content subtree when the prop changes.

Keep BottomSheetDraggableView as the stable wrapper. It already rebuilds its pan gesture with .enabled(enableContentPanningGesture), so gesture behavior remains dynamic without replacing the content tree.

Closes #2733.

Verification

• React identity regression harness: content mount count stays at 1 after toggling the prop
• yarn typescript
• yarn build
• yarn biome check --error-on-warnings src/components/bottomSheet/BottomSheetContent.tsx
• git diff --check

The repository-wide yarn lint still reports the existing unrelated optional-chain warning in src/hooks/useBoundingClientRect.ts:54.
