Remove hardcoded Redis configuration from config.exs

- Move Redis connection settings to runtime.exs only
- Remove localhost:6379 hardcoded values that were overriding runtime config
- Keep only non-environment-dependent Exq settings in compile-time config
- Fixes Exq trying to connect to localhost instead of Kubernetes Redis service
