ZEVA 2 - Textarea Input Field

**Describe the task**
Review the existing Textarea Input Field component in the UI library.
If a base Textarea component already exists, it should be updated to match the new Design System specifications documented in Figma.
If no suitable base component exists, a new reusable Textarea component should be created.

**Purpose**
To standardize multiline input fields across ZEVA 2 by ensuring that all textarea elements use a single, consistent component with shared styling, states, and behavior.

**Acceptance Criteria**
The component must support the following properties [(as defined in Figma)](https://www.figma.com/design/7Qgou3rxcHHk5qbmD9538x/ZEVA-2?node-id=210-443&t=T1mVHExNUezbW908-1):
- [x] Label: yes / no
- [x] Hint text: yes / no
- [x] Destructive: yes / no
- [x] State: default / hover / focus / typing / disabled / error
- [ ] Toolbar: yes / no
- [x] Button: yes / no
- [x] Error message: yes / no

Behavior & layout

Responsive width:
- [x] min-width: 280px
