[BUG REPORT] Portal Filters out Algorand GET requests

[blockjoe]

Technically Algorand uses REST and not RPC for their Blockchain API. All of the read based operations happen through GET, so currently, the only thing that the Portal is able to pass through to Algorand nodes is basically POSTing transactions.

For reference: the node API, and the indexer API.

Not all of these methods make sense exposed publicly, but MyAlgo currently maintains public endpoints that expose the methods on these APIs that make sense to expose public facing. For reference: the public node API and the public indexer API.
