Fix WebSocket client: switch to gorilla/websocket, add e2e tests

- Replace x/net/websocket with gorilla/websocket — the old library's
  stream-oriented framing was incompatible with Daptin's server
- Decode base64 response data (server sends []byte as base64 via JSON)
- Fix permission get: parse float64→int64, read from "data" not "attributes"
- Add relate/unrelate/ws to known commands for arg reordering
- Add 9 WebSocket e2e tests: ping, listen, subscribe, publish, topic
  create/delete/permission get+set, multi-topic subscribe
- E2e tests sign up a unique user per run and unset DAPTIN_ENDPOINT
  for ws commands so the saved auth token is used
