pangolin keeps polling - cpu is used

### Describe the Bug

While there is no traffic (also no blocked one) the cpu is constantly using about 5%
This is not a drama but maybe a chance of improvement.
I have no idea if this is by intention, if so, please close this issue.

### Environment

- OS Type & Version: Linux pangolin 6.17.2-2-pve #1 SMP PREEMPT_DYNAMIC PMX 6.17.2-2 (2025-11-26T12:33Z) x86_64 GNU/Linux (LXC on proxmox with docker containers)
- Pangolin Version: 1.14.1
- Gerbil Version: -
- Traefik Version: v3.6.4
- Newt Version: -
- CrowdSec: no version found, latest (Jan 2026)

### To Reproduce

top

...

The 'AI' says: indication for busy-polling, the event loop never sleeps.

### Expected Behavior

lower CPU when idle

Start from the MainThread process and reproduce the idle workload with top and strace as shown in the issue. Trace the event loop behavior around the repeated epoll_pwait calls, then verify that Pangolin uses less CPU when idle without traffic.
