Implement Blockfrost `/accounts/{stake_address}/history` endpoint

[whankinsiv]

Implement active stake processing and indexing by account in historical_accounts_state without sending the entire active stake distribution from accounts_state on epoch transition. This is the last unimplemented /accounts endpoint.

Example response:

[
  {
    "active_epoch": 210,
    "amount": "12695385",
    "pool_id": "pool1pu5jlj4q9w9jlxeu370a3c9myx47md5j5m2str0naunn2q3lkdy"
  },
  {

  }

Is this issue required for the Intersect milestones or can it be delayed until the new year?
