* fix: capitalize German 'Uhr' in 24-hour time format
- Conditionally apply toLowerCase() only for 12-hour format (AM/PM)
- Preserve proper capitalization for 24-hour format in German and other locales
- German 'Uhr' now displays correctly as 'Uhr' instead of 'uhr'
Fixes#24455
* refactor: remove code comments for clarity
* use ternary in return instead of mutable variable
* refactor: remove toLowerCase from time formatting
* addressed cubic suggestion
