Original GitHub issue: https://github.com/JakeStanger/ironbar/issues/1491

Describe the bug
When running under niri with one active external monitor and one disabled internal panel, ironbar sometimes creates two bars on startup. The extra bar is not kept on the disabled output; instead, it appears on the active monitor, so two bars end up rendered on the same physical screen.
This looks like an output-binding issue rather than just an extra-output detection issue.
To reproduce
Steps to reproduce the behavior:

Use niri as the compositor.
Have two outputs available:
- internal laptop panel (eDP-1)
- one external monitor
Make the external monitor active and the internal panel disabled.
Start ironbar.
Observe that sometimes two bars are rendered on the active monitor.
Expected behavior
If a disabled output is still reported by the compositor, ironbar should either:

bind the bar strictly to that output, or
not create/show a bar for that output at all
It should never render that extra bar onto another active monitor.
System information:
Distro: Arch Linux
Compositor: niri
Ironbar version: 0.18.0
Configuration

Config

```toml position = "top" end type = "clock"

Styles

/* default / irrelevant */

```
