Fix Firefox duplicate calendar icon with -moz-appearance: textfield

Browse Source 
The opaque background overlay approach didn't fully cover Firefox's
native icon. Instead, use @-moz-document url-prefix() to apply
-moz-appearance: textfield which strips all native date input chrome
(including the calendar icon) in Firefox. Safe because the DatePicker
provides its own custom popup. Removed the bg-background z-[1]
workaround from the custom button.
