Retire /ext/ endpoint prefix: /v1/ is THE endpoint

Route registration, client URL builders, and log lines all move to /v1/
(wallet primary api, chains/rpc handler_manager+chain_integration, xvm
client+wallet_client, xsvm api client, multi-network example, manager logs).
Zero /ext/ literals remain. One endpoint namespace, no transition alias.
