FormInputField::Integer doesn't handle 0n prefix

Version and Platform (required):

• Binary Ninja Version: 4.1.5246-dev
• OS: macOS
• OS Version: 14
• CPU Architecture: M1

Bug Description: The FormInputField APi for Integer fields doesn't respect the 0n1234 convention binja generally uses for numbers, nor does it use hex-by-default conventions either. We should make it match the integer parsing behavior seen elsewhere in the app.

Steps To Reproduce:

1. Run this python:

fi = IntegerField('int')
get_form_input([fi], 'a')
fi.result

2. Try to type 0n1234
3. Observe error box
4. Type 1234
5. Observe result is decimal 1234 and not 0x1234

Expected Behavior: I expected integer form inputs to match the rest of the product
