fix: capitalize German 'Uhr' in 24-hour time format (#25403)

* 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
