feat(installer): add xournal++ module, merge blender+povray, sync tui with simple
- Add apps/xournal.sh (xournalpp) wired into both installers
- Merge apps/blender.sh + apps/povray.sh → apps/blender-povray.sh; remove old files
- Sync tui-install.sh with simple-install.sh: add the 13 missing app modules
(gimp, inkscape, krita, ardour, audacity, lmms, mixxx, cecilia,
kdenlive, openshot, shotcut, anti-malware, timeshift) to checklist,
count_steps, summary, and run_module sections
