Incorrect parameter used for streaming response compression.

issue1:
Incorrect parameter used for streaming response compression.

root cause:
For `bidi_streaming` and `server_streaming`, the compression setting from the request side is passed to `encode_server`, whereas the header specifies `accept_encoding`.

issue2:
Infinite failover retries

root cause:
Err(_) => Some(future::ready(self.clone())),
Unlimited retries for any error, with no upper limit and no error categorization.

Trace the bidi_streaming and server_streaming paths to encode_server and compare the compression setting with the accept_encoding header. Then inspect the failover branch containing `Err(_) => Some(future::ready(self.clone()))` and determine the intended retry limit and error handling. Done means both compression selection and retry behavior are covered by tests, with no unbounded retries.
