• Updated balance processing functions to perform one insert for each range instead of one insert for each operation. Added limits for REST API.
• Fixed OpenAPI examples by removing extra [].
• Used cross joins in operation gathering queries, which improved performance by about 9%.
• Added daily and monthly aggregation for the historical changes in account balances within the processing function.
• Added new APIs:

/accounts/{account-name}/aggregated-history - returns daily/monthly/yearly balance changes

/accounts/{account-name}/delegations - returns incoming/outgoing delegations
