Fedora installer, cleanup and screenshots

- install.sh rewritten for Fedora: dry-run, --check, backups, oh-my-zsh, lazygit, swappy
- outputs-setup.sh (monitor layout for new hardware) and doctor.sh (health check)
- screenshot.sh: region / full / window / scroll / last / edit (swappy), saved and copied
- remove waybar, swaync, dunst, rofi and their helper scripts, wallpaper picker, mirror.sh
- wallpapers handled by DMS; keep only the favourite one
- 00-session.conf for portals; swayfx-only layer rules split into 21-dms-effects.conf
