[FIX] web: numpad decimal with number type

Steps to reproduce:
- in Barcode > Inventory Adjustment
In the quantities add a decimal numpad

Issue:
Traceback

Cause:
The field is from type=number. This kind of field does not accept methods such `selectionStart()` or `selectionEnd` which causes an error: https://html.spec.whatwg.org/multipage/input.html#do-not-apply

Solution:
When of type=number, just return.
On Chrome, numpad won't be possible for regions such as Portugese - BR. They would have to use the keyboard key `period`, code '.' in order to be able to put a decimal via the keyboard.
In Firefox, HTML is parsing the input correctly if the browser settings are set to the right localization. https://developer.mozilla.org/en-US/docs/Web/HTML/Element/Input#localization
