InputNumber: "-" sign on empty input is ignored

Describe the bug

When the InputNumber field is empty, focusing it and pressing the minus (-) key to enter a negative number causes 0.00 to be inserted automatically, and the caret jumps to the end of the input. As a result, it's impossible to enter a negative value directly. The user must first select and delete the entire 0.00 value and only then can enter a negative number.

I know that It worked correctly in PrimeReact v10.8.4.

Steps to reproduce the behavior

1. Open reproducer. There will be an empty number input.
2. Focus it and type "-"

Actual result: "0.00" appears in the input, caret stays in position after the decimal point

Expected behavior

"-" should be displayed in the input, caret stays at the end of the input

Start with the linked CodeSandbox reproducer and the PrimeReact InputNumber implementation, focusing on the empty-input path when the minus key is pressed. Confirm that the field keeps the '-' and the caret remains at the end without inserting 0.00, then verify the expected behavior across the listed browsers and versions.
