P: Convert Photos to DNG not respecting uppercase ".DNG" file extension

[zykohl]

Converting .DNG to .DNG files creates new files with lowercase ".dng" extension instead of ".DNG" extension, even if file extension in modal is set to "DNG".

Reproduced by trying to convert photos that were already in DNG format, e.g. from Leica Q2 or Leica M11. This previously worked fine in past versions of Lightroom Classic.

This is also a problem because the new files get different createdAt and modifiedAt timestamps in apple finder, which is undesirable.

Operating System: Mac OS 15.3.1

Lightroom Classic version:

I see the misbehavior in LR 14.2, 14.1.1, 13.5.1, but not in 12.0. It only happens when I select Delete Originals After Successful Conversion; it doesn't happen when it's unselected.

Precise steps to reproduce in LR 14.2 / Mac OS 15.3.2:

1. Select a raw file.

2. Do Library > Convert Photo To DNG with these options:

Observe the newly generated DNG has the extension "DNG" (correct).

3. Select the newly generated DNG and do Library > Convert Photo To DNG again with these options (selecting Delete Originals):

Observe the newly generated DNG has the extension "dng" (incorrect).
