Add /address/:addr/txs/summary endpoint

[mononaut]

This PR adds a new /address/:address/txs/summary/(last_seen_txid?) endpoint which returns a condensed list of recent confirmed transactions related to an address combined with the blockheight, time, and net balance change.

The endpoint is paginated using the usual last_seen_txid format, with a maximum number of transactions configurable via --rest-default-max-address-summary-txs (default 5000).

Results are returned in the following format:
