feat(hyprland): Refactor workspaces and add blur effect

Refactor Hyprland configuration to:
- Move Steam and Music from special workspaces to unique, named workspaces for better integration into the regular workflow.
- Update Waybar's workspace module to correctly display icons for these new named workspaces and filter them out from the special workspaces module.
- Implement a global blur effect for inactive windows, with a specific exception to keep Firefox windows fully opaque, enhancing focus on active content.
