### TL;DR
Refactored the `DomainCard`, `EditDomainDialog`, and `WebhookCard` components to improve code readability and enhance UI using new shared components like `Tag`, `Heading`, `Button`, and `CustomIcon`.
### What changed?
- `DomainCard` component:
- Replaced `Chip` with `Tag` component.
- Used `Heading`, `Button`, and `CustomIcon` components.
- Updated refresh icon to show `LoadingIcon` when checking.
- `EditDomainDialog` component:
- Used `useToast` hook for toast messages.
- `WebhookCard` component:
- Used `Input`, `Button`, and `CustomIcon` components for better UI.
- Added Storybook stories for the updated components.
### How to test?
1. Go to the project settings page.
2. Verify the `DomainCard` UI updates.
3. Edit a domain and check the toasts.
4. Verify the `WebhookCard` UI and functionality.
5. Run Storybook and inspect the added stories for the components.
### Why make this change?
To improve the consistency and user experience of the project settings UI, and to make the components more maintainable by using shared components.
