Subject: [PATCH] Fix Redis authentication error - don't send empty password
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Only include password in Exq config if it's not empty
- Prevents "ERR AUTH <password>" error when Redis has no authentication
- Build config dynamically to exclude empty password field
