Enatega Customer Application: Make Add a Message for Restaurant whole field clickable rightnow user has to click the arrow button

Describe the bug
Currently, on the "Add a Message for Restaurant" component, only the arrow button is clickable to expand or activate the input field. Users must specifically click the arrow, which is not intuitive and can lead to confusion or missed interaction. Clicking anywhere within the field area should trigger the same behavior.

Steps to Reproduce:

Navigate to the section with "Add a Message for Restaurant."
Attempt to click on the text or empty area of the field (not the arrow).
Observe that nothing happens unless the arrow button is clicked.
Expected behavior
The entire "Add a Message for Restaurant" field (including the text and surrounding container) should be clickable to expand the input area, not just the arrow button.

Smartphone (please complete the following information):

Device: [e.g. Infinix HOT 50]
OS: [e.g. Android]
Browser [e.g. Application]
Version [e.g. Latest]

The issue does not name a file or test; start by searching the frontend for the "Add a Message for Restaurant" text and inspect the component's expand behavior. Verify that clicking the text or surrounding field opens the input, while preserving the existing arrow behavior, and test the interaction on the restaurant ordering screen.
