✨ Add service disclaimer component and Nostr validation links

- ➕ Introduced reusable `<x-service-disclaimer>` component for better clarity and consistency on service pages.
- 🔗 Added `njump` links for Nostr profile validation in service listings and landing pages.
- 🧪 Included feature tests to verify disclaimer visibility and correct `njump` link rendering or omission for anonymous services.
