fix(fleet): add redis-server dependency

Fleet requires Redis for live queries, async jobs, and distributed
locking. Without it the fleet serve process fails on startup.

- Install redis-server package
- Add FLEET_REDIS_ADDRESS=127.0.0.1:6379 to .env
- Add redis-server.service to systemd After/Requires
- Enable redis-server alongside fleet service
