feat(client,prospect): add warning variant to TextArea (#1803)

[Debaerdm]

Add a warning variant to the TextArea component (Apollo + LF), consistent with the warning variant introduced on InputText, InputDate, and Dropdown.

Trigger the warning state by passing message together with messageType="warning". A new af-form__textarea--warning class is applied to the textarea, styled with the orange-1050 token (2px inner shadow by default, 3px on hover/focus/active). The existing :not(:placeholder-shown) blue override is still overridden correctly because the warning selector comes later and has equal specificity.

Closes #1803

Retours appliques dans le commit 7c84c57 :

• TextAreaCommon.tsx utilise maintenant la fonction getClassName avec modifiers (hasWarning && "warning"). Ajout de la prop classModifier pour rester coherent avec les autres composants (InputDate, etc.).
• Bloc &[class*="--warning"] deplace dans TextAreaCommon.css, supprime de TextAreaApollo.css et TextAreaLF.css (les deux themes utilisaient exactement --orange-1050).

Les valeurs aria-invalid restent per-theme car elles different (red-alert-1000 Apollo vs red-alert-1200 LF).
