Prevent typing beyond max value in Progress Input

What does this MR do and why?

Progress input field within Work Items (currently only available for OKRs) has max config set to 100, but it is only enforced until user doesn't use keyboard to input the values, if user uses numeric keys on keyboard, they can easily type in values above 100, which is invalid behaviour. This MR fixes it by guarding the input in keyup event, because input[type="number"] doesn't do it for us! ☹
