vaani : refactor: Update pool URL in HomeView.vue

This commit updates the pool URL in the HomeView.vue component to use 'https://alberti.besoeasy.com/graphql' instead of 'https://pool.albertiprotocol.org/graphql'. This change ensures that the app fetches server info from the correct endpoint, providing accurate data to the users.
