fix: resolve failing test assertions

Fixed 2 failing tests that were introduced by conditional expect fixes:

1. year_picker_test.test.tsx - "should call updateFocusOnPaginate":
   - Changed test to navigate from last year element to trigger pagination
   - Added yearItemNumber prop to ensure consistent year grid
   - Now properly tests the requestAnimationFrame call in updateFocusOnPaginate

2. timepicker_test.test.tsx - "should not call onChange when clicking disabled time":
   - Increased number of excluded times to ensure at least one is rendered
   - Added timeIntervals={60} for better disabled time visibility
   - Now reliably tests the disabled time click behavior

Coverage improved: 98.78% → 98.81% statements

All 1,203 tests passing ✓
