Reviewer's Guide

This PR fixes the upload component so that when it is disabled (IsDisabled = true), clicking the browse button no longer opens the file selector by adding a guard in the click handler for the browser button in the JavaScript module.

Hey - I've left some high level feedback:

• In the click handler, instead of querying el.querySelector('.btn-browser') each time, cache the button element once during init and reuse it for both the disabled check and binding.
• Relying solely on the disabled CSS class to block interaction may be brittle; consider checking the actual disabled attribute/state on the button or a single source of truth flag on el so the JavaScript behavior cannot drift from the visual state.
