Streamline latest block access & finalized block caching

[nounder]

• Cache finalized block fetching globally. Before getBlock RPC call was made for every getAccountHistory request. Now the value is refreshed at most once every 1s. More: #1180
• Fix a bug where AccountHistoryResult could be one block behind. Now we get latest indexed block from Shovel database instead from internal Watcher indexer in getAccountHistory. This bug occurred when event loop called a new block notification callback in Watcher.watch before one in onAccountUpdate TRPC subscription.
