Fix all issues from code/UX review

ISO structural:
- Move post-install.sh → airootfs/etc/calamares/ (it was never in the squashfs)
- Create airootfs/etc/skel/.config/ with all dotfiles (deploy path now works)
- Add iso/pacman.conf with [breadway] custom repo stub for calamares + bakery
- Add Calamares branding component (bos/branding.desc + show.qml)
- Add missing unpackfs.conf and mount.conf modules
- Add live-session autostart: getty autologin → bash_profile → Hyprland → calamares
- Add polkit rule for wheel-group snapper rollback (pkexec path)
- Remove wlroots from packages (bundled with Hyprland); add bakery to package list
- Fix modules-search path in settings.conf

Dotfiles:
- Rename dotfiles/hyprland/ → dotfiles/hypr/ (Hyprland reads ~/.config/hypr/)
- Fix deprecated shadow options: drop_shadow/shadow_range → shadow { } block

bos-settings Rust:
- Replace glib::MainContext::channel (removed in glib 0.19) with async_channel
- Stream bakery update output line-by-line instead of buffering all at once
- Fix zombie processes: per-package update buttons now wait() in a thread
- Fix sidebar/stack mismatch at startup: select snapshots row to match default view
- Replace deprecated MessageDialog with AlertDialog (GTK 4.10+) throughout
- Use pkexec for snapper rollback so polkit handles privilege escalation
- Add confirmation dialog before delete snapshot (was missing, rollback had one)
- Add refresh button + repopulate after delete in snapshots view
- Add "Saved" / "Error: …" status label to every config view save button
- Add "Remove" buttons to breadbox contexts and breadcrumbs profiles
- Remove hardcoded model string from breadpad defaults
- Drop unused state mod; fix config_dir HOME fallback; fix zombie in editor launches
