Update rev-gateway for IAM integration (#940)
service.py:
- Constructor takes **config (same pattern as api-gateway) instead
  of individual args
- Creates IamAuth and calls await self.auth.start() before the
  message loop
- Passes auth to both ConfigReceiver and MessageDispatcher
- Uses add_pubsub_args / add_logging_args instead of hand-rolled
  Pulsar args
- Passes timeout through

dispatcher.py:
- Accepts auth and timeout parameters
- Passes both to DispatcherManager — fixes the missing auth argument
  that would have crashed on startup

The remote end's requests now go through the same IAM authentication
path as api-gateway. Token validation, workspace resolution, and
permissions all work identically regardless of which direction
initiated the connection.

Fixed tests — the test now passes auth and timeout to MessageDispatcher
and verifies they're forwarded to DispatcherManager.

Update rev gateway dispatcher to align with IAM.  A "token" parameter
must be passed with each message.

Fix websocket relay to align with rev-gateway changes, conforms to
the api-gateway protocol.
