Omarchy Theme Installer (#150)

* Add omarchy theme remove

* Add theme installer

* Add migration to make theme management scripts executable

* Refactor theme installation script to simplify directory structure and remove unnecessary symlinks.

The script now directly clones themes into the ~/.config/omarchy/themes directory and updates paths accordingly for backgrounds and fonts.

* Update permissions for theme scripts and remove unnecessary migration file

* Refactor theme installation script to always use swaybg-next

* Remove fonts from omarchy-theme-install

* Refactor omarchy-theme-remove by swiitching to theme dir and removing unnecessary symlink checks

* Refactor theme installer to use omarchy-theme-set

* Fix Omarchy theme remove removing current theme and throwing error

* Making theme management scripts quiet
