Wallet age & freshness signal API

Derive a wallet's first-transaction date, lifetime transaction count, and age in days from a keyless block explorer, then score a single freshness verdict (empty / fresh / new / established / veteran) an agent can branch on for risk. Turns a raw tx list into one risk-grade signal. Answers 'how old is this wallet', 'is this a brand-new wallet', 'first transaction date of this address', 'wallet freshness risk signal'.
