Cut 'coinos' data source over to our own Fulcrum (Electrum)

Flip COINOS_ELECTRUM on: the default 'coinos' mode is now a full Electrum backend
served same-origin at wss://halwallet.app/electrum (nginx -> Fulcrum on cs, synced
+ using bitcoind hashblock ZMQ), with the public Electrum servers as automatic
failover. Replaces the explorer-REST-data + coinos-watcher-push setup — one
connection to our own node now serves both data and instant notifications.
Verified the endpoint end-to-end through Cloudflare (server.version + get_balance).
