hyprland/uwsm: part 1

Switch to UWSM to automatically manage systemd session.

Many services wrongfully require `graphical-session-pre.target` while
also requiring WAYLAND_DISPLAY to work. Will need to change this in HM.

Part 2 will encompass switching from run-as-service (see
home/terminal/programs/transient-services) to `uwsm app` or some
[other helper](https://github.com/Vladimir-csp/app2unit).
