Refactor chat and market modules for improved integration and maintainability

- Remove deprecated Nostr chat and relay hub components, transitioning to a modular chat service for better encapsulation.
- Update App.vue and Navbar.vue to utilize the new chat module, enhancing user experience with automatic peer management.
- Simplify event handling and connection logic in ChatComponent.vue, ensuring compatibility with the new chat service architecture.
- Adjust market settings and order history components to reflect changes in the chat module, improving overall coherence in the application structure.
- Clean up unused imports and streamline configuration access for better performance and maintainability.
