chore: remove leftover Redis infrastructure code

Dokploy stopped using Redis in v0.29.9 when the deployment queue moved
to an in-memory implementation, and install.sh no longer creates the
dokploy-redis service. Remove the remaining references so fresh installs
don't report Redis as unhealthy:

- checkRedisHealth from infrastructure health check
- cleanRedis/reloadRedis endpoints and their UI actions
- initializeRedis dev setup and redis-connection config
- unused bullmq dependency
