Refactor market components for improved structure and functionality

- Update imports in DashboardOverview.vue to use relative paths for better module organization.
- Modify OrderHistory.vue to replace 'lightningInvoice' with 'paymentRequest' for consistency in payment handling.
- Enhance order event handling in useMarket.ts by adding subscription and decryption logic for order-related DMs.
- Update nostrmarketService.ts to use relative imports, ensuring consistency across the module.
- Introduce error handling and logging for order updates, improving the robustness of the market module.
