algod: Delete v1 usage from client and remove V2 prefix from APIs

[algochoi]

Summary

This PR removes

• v1 algod usage for the internal REST client and any tests that test v1-exclusive APIs like TransactionByAddr.
• legacy/deprecated goal commands that reference v1-exclusive APIs

The PR also removes the V2 prefix from client APIs, since we do not have to distinguish between v1 and v2 algod APIs.

Test Plan

CI Tests.
