[DB] Addresses lower/uppercase shouldn't matter

[bitbeckers]

We need to restore the ilike functionality, i.e. case unsensitive search, to fix the current querying set up:

 const queryRes = await request(HYPERCERTS_API_URL_GRAPH, query, {
      where: { creator_address: { eq: creatorAddress.toLowerCase() } },
    });

  const queryRes = await request(HYPERCERTS_API_URL_GRAPH, query, {
      where: { fractions: { owner_address: { eq: getAddress(ownerAddress) } } },
    });

It appears that the addresses are stored using different formats, but regardless the API shouldn't care to facilatate easier querying

This is done, right @bitbeckers?
