feat: Enhance RelayHub component with subscription count details (still not working)

- Update RelayHubStatus.vue to display both local and global subscription counts, improving user visibility into active subscriptions.
- Add totalSubscriptionCount computed property in useRelayHub.ts to track the total number of subscriptions.
- Implement totalSubscriptionCount getter in relayHub.ts to return the size of the subscriptions map.
- Include debug logging in relayHub.ts for connected relay counts and statuses to aid in troubleshooting.
