Strict API: type component refs with React.ComponentRef #101816

Part of #101439.

Do not enable customConditions here. React.ComponentRef<typeof X> typechecks on the current config and under the Strict API, so this does not have to wait for the opt-in.

Incompatibility

Core components are typed as function components under the Strict API, so useRef<TextInput> refers to the component function and instance methods like .focus() are missing. Animated.LegacyRef<View>, NativeMethods, and NativeMethodsMixin are removed.

The *Instance types (TextInputInstance, ViewInstance, …) are the 0.87+ spelling. They are not exported on 0.86, so they cannot be used yet.

Known call sites, re-check after the ThemeStyles fix since several ref errors in the opt-in log were that cascade:

• src/components/EmojiPicker/EmojiPickerMenuItem/index.native.tsx — .focus() missing
• src/components/AnimatedSubmitButton/index.tsx — View | null ref assigned to an Animated.View
• src/components/AvatarCropModal/ImageCropView.tsx — same
• src/components/ActionSheetAwareScrollView/useActionSheetAwareScrollViewRef.ts — reanimated ref against PublicScrollViewInstance
• src/components/Charts/components/ChartTooltip.tsx

Fix

Replace every component name used as an instance type with React.ComponentRef<typeof Component>: useRef / createRef type arguments, forwardRef type arguments, and ref props on wrappers.

Animated.LegacyRef<View> → the same ComponentRef form. NativeMethods / NativeMethodsMixin → HostInstance, or the specific ComponentRef.
