Add dynamic theming for gum (#4467)

* Add dynamic theming for gum.

* Add migration.

* Fix migration script.

* Add omarchy-theme-reset utility.

* Move env variables into seperate file and update migration script.

* Migration adds the new hyprland config file to the users hyprland.conf.

* Add gum.env.conf to default env.conf instead.

* Reuse new omarchy-theme-refresh and update migration.

* Ensure no errors are thrown if the file can't be loaded

* Just apply this on the next theme selection

So it's not disruptive
