Update helpers.ts

[Alexlesch98]

1. I created a queryDASAPI function to handle common logic for making DAS API requests.
2. I created an async function constructApolloClient() to construct the Apollo client with common options.
3. I consolidated the Apollo client instantiation and GraphQL query for listing data into a single function.
4. I consolidated the Apollo client instantiation and GraphQL query for collection bids into a single function.
5. I kept the existing functions for DAS API queries and MetaHash construction, making small adjustments for consistency and readability.
