Co-authored-by: Copilot <copilot@github.com>

* Revert "Add check for active external monitors before disabling internal display"

This reverts commit e20b3da87e3df0f084c0bca232a61ba58fab4cdc.

* feat(hyprland): add toggle for internal monitor mirroring

- Implement `omarchy-hyprland-monitor-internal-mirror` to dynamically mirror the internal eDP display to external monitor.
- Update `omarchy-hyprland-monitor-internal` to prevent disabling the laptop screen if mirroring is currently active.
- Add "Mirror Display" toggle to omarchy hardware Menu

* Ensure there is also a laptop monitor available to mirror before we do it

* Fix toggle use

* Recover from mirror mode gracefully

* Add hotkey to mirroring
