Fix Replicated cache data loss on rolling deploy

Replace anonymous function with MFA call in Bootstrap.stream_entries/3.

During rolling deploys, the new node sends a lambda via :rpc.call to
copy cached entries from existing nodes. Lambdas are bound to the
sending node's module version and fail on nodes running different code,
producing {:badrpc, _} which is silently swallowed. The new node starts
empty, and remaining nodes copy from it, causing total data loss.

The fix uses an MFA call to a public do_stream_entries/1 function
instead. MFA calls resolve on the remote node using its own code,
so they work across code versions.
