Feat/add remaining alerts for drive path selection

[egalvis27]

What is Changed / Added

---

• Added a dedicated validation module for virtual drive root changes.
• The new validation blocks mounting the drive on removable devices, folders that belong to other cloud providers, and paths with insufficient permissions.
• Added specific error codes so the UI can show a different notification for each failure case.
• Updated the Settings flow to handle the new result contract and avoid overwriting the current valid path when the selected one is rejected.
• Added French, Spanish, and English translations for the new notifications.
• Expanded unit tests for the new validation module and the updated service flow.

Why

---

• To prevent users from changing the drive path to unsafe or unsupported locations.
• To avoid breaking the current working mount path when the new path cannot be used.
• To give users clear, specific feedback depending on why the path change failed.
