Fixes: #16872 ## Summary Fixes the DateTimePicker to respect user's 12H/24H time format preference. Previously, the time display at the top of the DateTimePicker always showed 24-hour format (e.g., "14:30") regardless of the user's time format setting. ## Screenshots _After:_ Time respects user preference, showing 12H with AM/PM (e.g., "03:28 PM") or 24H format <img width="357" height="491" alt="image" src="https://github.com/user-attachments/assets/4a03f195-a52b-4f74-84ba-c5eb2fc6c8c1" /> ## Implementation Details ### Changes Made: 1. **TimeMask.ts** - Added `getTimeMask()` to return appropriate mask pattern based on time format 2. **TimeBlocks.ts** - Restored as constant file per linting requirements 3. **getTimeBlocks.ts** (new) - Dynamic block generator supporting 12H (1-12 + AM/PM) and 24H (0-23) 4. **DateTimeBlocks.ts** - Simplified to static constant 5. **getDateTimeMask.ts** - Updated to accept and use `timeFormat` parameter 6. **DateTimePickerInput.tsx** - Dynamically generates mask and blocks based on user's time format preference, increased input width to accommodate AM/PM 7. **useParseJSDateToIMaskDateTimeInputString.ts** - Formats dates with correct time pattern 8. **useParseDateTimeInputStringToJSDate.ts** - Parses dates with correct time pattern 9. **date-utils.ts** - Added `getTimePattern()` helper (returns 'hh:mm a' for 12H, 'HH:mm' for 24H) 10. **parseDateTimeToString.ts** - Added optional `timeFormat` parameter for consistency ### Technical Approach: - Leverages existing `useDateTimeFormat()` hook to get user's `timeFormat` preference - Supports `TimeFormat.SYSTEM`, `TimeFormat.HOUR_12`, and `TimeFormat.HOUR_24` - Uses IMask blocks with appropriate ranges: 1-12 for 12H, 0-23 for 24H - Adds 'aa' (AM/PM) block for 12-hour format with enum validation --------- Co-authored-by: Lucas Bordeau <bordeau.lucas@gmail.com>
