fix(replication): surface HTTP 413 via paused/error events

[Mayankaggarwal8055]

Fixes #9165

HTTP 413 (Content Too Large) from CouchDB _bulk_docs during live replication was silently retried via backOff() instead of surfacing through paused(err) events as users expect.

Solution: In completeReplication(), treat 413 as fatal - emit paused(error) + error(error) and stop retrying.

Changes:

+ } else if (fatalError.status === 413) {
+   returnValue.emit('paused', fatalError);
+   returnValue.emit('error', fatalError);
+   returnValue.removeAllListeners();
+ } else {
    backOff(opts, returnValue, fatalError, function () {
      replicate(src, target, opts, returnValue);
    });

Hi @janl @alxndrsn @SCdF ,

This PR addresses issue #9165 by surfacing HTTP 413 errors during live replication through paused(err) and error(err) events instead of silently retrying.

Currently the workflow is awaiting maintainer approval before CI can run.
Whenever you have time, could you please take a look and approve the workflow so the checks can start?

Thanks!
