The live pipeline was receiving trade data and populating Redis caches but
never persisting wallet profiles or funding transfers to Postgres. This
wires the repositories into the _on_trade flow: when a fresh wallet signal
is detected, the wallet profile is upserted to wallet_profiles and the
funding chain is traced and inserted into funding_transfers. Existing
Redis caching behavior is preserved.
