Reconsider "idle-dim" feature
Following the changes to idle-dim in GNOME 41, we should consider whether we want to:
- remove idle-dim and always dim when possible
- whether we should screensave harder instead of dimming
- whether dimming after half the timeout to screensave is aggressive enough
- whether users expect the "power-saver" dimming to be something that should get disabled by the "idle-dim" option
