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]

"Add a Message for Restaurant" というテキストを含む customer-application コンポーネントを見つけ、矢印ボタンによってフィールドがどのように展開されるかを確認します。フィールド領域全体で同じ動作が発生するようにし、その後、テキスト、空白の領域、矢印をクリックすると、想定どおり入力欄が展開されることを確認します。
