seems good, only change top delete button color to $pureWhite should work for both dark and light theme..

@aliseyalvi more feedback on this...

Long press draft entry delete button should also initiate batch delete selection process

If I delete a pre selected draft item, and then batch delete drafts, it throws a failure toast, which does not affect the functionality but confuses users..

Another feedback regarding selection mark, perhaps red border is still too much, may be make the draft entry delete button on red instead. tapping delete button to deselect should also fix the above mentioned issue.

Last, change top batch delete button icon color to white...

match color, if possible reuse this delete button as component and move it under components/atoms directory if not already there... if not smoothly possible just update color.

@noumantahir reverted delete icon color to primaryBlack as uploadGalleryModal is also using the same color
