## PR-Codex overview
This PR focuses on improving the handling of contract addresses in the `CreateWebhookModal` and `FilterDetailsStep` components, as well as refining validation logic for addresses in `webhookTypes.ts`. It enhances user experience by clarifying requirements and allowing optional inputs.

### Detailed summary
- In `CreateWebhookModal.tsx`, the `addresses` property now defaults to an empty string if not provided.
- In `FilterDetailsStep.tsx`, the `FormLabel` for "Contract Addresses" and "To Address" no longer includes a required indicator.
- Validation in `webhookTypes.ts` for `addresses`, `fromAddresses`, and `toAddresses` is updated to allow empty inputs and provide clearer error messages.
