59f7582463 Fix: time format issue in datepicker mask (#16922)
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

## 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
