Subject: [PATCH] [ADD] inventory: Improve stock info and UI in product form
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Before:
Users could easily get confused or make mistakes when managing stock,
especially in multi-company environments. Important actions like
updating quantity on hand were hard to find, and the interface didn’t clearly
guide safe workflows.

After:
The interface now better supports new users by reducing confusion and
make stock workflows safer. Risky actions are hidden if not appropriate, visual
clarity helps users avoid errors and understand inventory status more easily.
