refactor(personalization): move user settings to dotfiles

[DevSecNinja]

Summary

• remove the 14 current-user, non-admin personalization entries now owned by chezmoi in feat(windows): apply current-user personalization dotfiles#711
• remove the opinionated profile's implicit US-International Autounattend keyboard default while preserving explicit installer locale, keyboard, and timezone configuration
• refresh profile documentation, ordering/selection/schema expectations, and the generated 53-entry catalog manifest

Ownership boundary

DevSecNinja/dotfiles now owns current-user personalization that can run online without elevation. windows-iso-maker continues to own offline servicing and machine-wide/admin behavior: Start web-search and clipboard policies, Recall policy/component removal, WSL and Virtual Machine Platform, service/time/hibernation settings, Surface power policies, timezone configuration, and the reverse-scroll SYSTEM scheduled task.

Coordinated with DevSecNinja/dotfiles#711 (commit a8fb9ce).
