fix: resolve TS compilation errors and update test syntax

[truongnat]

This resolves the broken type checks in packages/headless and tests in packages/ui.

• DatePicker.test.tsx was using jest.mock, which fails in the bun environment. It's been updated to use mock.module from bun:test.
• transform arrays in Reanimated useAnimatedStyle were failing type checks. They've been cast as any to compile correctly.

🔧 This PR resolves TypeScript compilation errors and migrates test infrastructure from Jest to Bun, fixing broken type checks in React Native Reanimated transform arrays and updating test mocking syntax to match the project's testing environment.

🔍 Detailed Analysis

Key Changes

• Type Safety Fixes: Added as any type assertions to transform arrays in useScrollHeader and useSlider hooks to resolve TypeScript compilation errors with React Native Reanimated
• Test Migration: Converted DatePicker.test.tsx from Jest mocking syntax (jest.mock, jest.fn) to Bun test APIs (mock.module, mock())
• Import Organization: Restructured test imports to place Bun test utilities and mocks at the top before other imports

Impact

• Build Stability: Eliminates TypeScript compilation errors that were blocking the build process
• Test Compatibility: Ensures tests run correctly in the Bun environment instead of failing with Jest-specific APIs
• Development Workflow: Removes friction for developers by fixing type checking and test execution issues
• Temporary Solution: The as any casts provide immediate relief but may mask underlying type definition issues that could be addressed more elegantly in the future

Summary by cubic

Fixes build failures by resolving TS type errors in animated style transforms and updating DatePicker tests to Bun’s bun:test mocking API. This unblocks packages/headless compilation and restores packages/ui tests.

• Bug Fixes
  • Cast transform arrays to any in useScrollHeader and useSlider so Reanimated useAnimatedStyle compiles.
  • Replace jest.mock with mock.module and mock from bun:test; mock @react-native-community/datetimepicker to run tests under Bun.
