[Fix] Redis hyperscan cache: use write_servers for store/delete operations

The redis_backend was missing is_write=true in attrs for store and delete
operations, causing lua_redis.request to use read_servers instead of
write_servers. This resulted in READONLY errors when read and write servers
are configured separately.
