Remove the forced number key pad

A few months ago an update was made to the App which now force opens number keypads in certain areas of the manifest and close manifest pages instead of the regular keyboard.

This keypad swap is very clunky to tap in and out of, and it many times covers the text box you are entering number to.

I feel this change has only caused issues and delays in entry of flight data compared to leaving the normal ipad keyboard as default.
