feat: port dinosaur ujust from aurora

[Copilot]

This implements the toggle-dinosaurs functionality from Aurora PR #690, allowing users to enable/disable automatic monthly dinosaur wallpapers for KDE Plasma.

What's Added

Package Support: Added plasma-wallpapers-dynamic package to the KDE section in Containerfile to provide the com.github.zzag.dynamic wallpaper plugin required for dynamic wallpapers.

Systemd Service: Created [email protected] template service that automatically downloads and updates wallpapers monthly. The service accepts a hemisphere parameter (north/south).

Download Script: Added /usr/libexec/ublue-bluefin-plasma-wallpaper executable script that downloads wallpapers from the plasma-bluefin-wallpaper repository, using MD5 checksums to avoid redundant downloads.

Ujust Recipe: Added toggle-dinosaurs recipe to 80-bazzite.just with interactive enabling/disabling, hemisphere selection, automatic KDE wallpaper plugin configuration via qdbus, and proper status checking.

Usage

ujust toggle-dinosaurs        # Interactive mode for north hemisphere
ujust toggle-dinosaurs south # Interactive mode for south hemisphere

The recipe will:

• Check current service status
• Allow enabling/disabling the monthly wallpaper updates
• Automatically configure KDE Plasma to use the dynamic wallpaper plugin
• Download wallpapers to ~/.local/share/wallpapers/Bluefin/
• Set up systemd user service for automatic monthly updates

Technical Details

The implementation uses KDE's dynamic wallpaper system through the com.github.zzag.dynamic plugin, which requires the plasma-wallpapers-dynamic package. Wallpapers are downloaded from the Bluefin project's monthly dinosaur wallpaper releases and configured automatically via qdbus commands.

Fixes #3056.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled

This is all KDE specific, none of those files need to be in the shared directory.

the actual just recipe only needs to be shown on KDE. It would be broken on gnome
