feat: add power menu

[brckd]

Adds a power menu with configurable entries. Repurposes the previous power button. Lets you reboot and power off by default. Other options are not available by default because they have dependencies like systemctl or uwsm.

The entries are configurable via the settings.json or similarily in Nix:

{
  "powerMenuEntries": [
    {
      "label": "Restart",
      "command": "reboot",
      "confirmation": "Are you sure you want to restart the computer?"
    },
    {
      "label": "Power Off",
      "command": "shutdown now",
      "confirmation":"Are you sure you want to power off the computer?"
    }
  ]
}

Here's also a list of useful commands when configuring these entries:

command	usecase
systemctl suspend	Suspend using SystemD
systemctl reboot	Restart using SystemD
systemctl reboot --firmware-setup	Restart to UEFI using SystemD
systemctl poweroff	Power off using SystemD
uwsm stop	Log out using UWSM
hyprctl dispatch exit	Log out of Hyprland without UWSM

Thank you for the PRs! I am currently on vacation and don't have my PC with me, so I won't be able to test this for a week or two. Sorry for the delay.

I'm on vacation as well, so no pressure. I just use my fork in the meantime.

Great work! The code looks good, I just have some minor style nits.

[brckd]

Thanks for the review! I'll look at it when I'm home in a week.

I noticed some weird layout bugs when trying this on my laptop. I'll take a deeper look at them tomorrow.

That bug was unrelated and I opened #26 for it.

The biome configuration doesn't work with the latest version of biome, so I hope manually formatting it worked.

Looks like mithril-shell.nix is also formatted incorrectly according to the CI

[andreashgk]

Hi, any update on this? I can't format the file in this PR as I don't have push permission I believe

[brckd]

Sorry for the delay. I hope this fixes it!
