### Description

Attempting to launch io.trezor.suite (Flatpak) via Spotlight doesn't open the app but creates the processes. This only happens when DMS is run as a service. Running DMS with `dms run` doesn't cause this issue. Running the app via gtk-launch, flatpak run or fuzzel works fine.

### Expected Behavior

The app opens like any other app/flatpak

### Steps to Reproduce

1. Run DMS as a service
2. flatpak install io.trezor.suite
3. Open spotlight and open Trezor Suite

### Error Messages/Logs

Journalctl --user -u dms.service -f shows nothing when opening apps via Spotlight.

Sway is run via systemd

```
cat .config/sway/conf.d/systemd.conf
exec dbus-update-activation-environment --systemd --all XDG_CURRENT_DESKTOP=sway"
exec "systemctl --user import-environment {,WAYLAND_}DISPLAY SWAYSOCK"
exec systemctl --user start sway-session.target

systemctl --user status sway-session.target

### Screenshots/Recordings

_No response_

Start by comparing DMS as dms.service with dms run, then reproduce launching io.trezor.suite from Spotlight while monitoring journalctl --user -u dms.service -f and the listed Sway/systemd environment setup. Trace the Spotlight launch path and service environment; done when Trezor Suite opens through Spotlight under the service just as it does via gtk-launch, flatpak run, or fuzzel.
