UX: Move "View target details" to sub-menu under List targets

Improved menu flow by moving target details viewing into a natural
workflow after listing targets.

BEFORE:
Main menu had 8 options including separate "View target details" option.
User flow: Main → List targets → Main → View details → Select target

AFTER:
Main menu has 7 options. "View target details" is a sub-menu.
User flow: Main → List targets → View details (optional) → Main

CHANGES:
- Option 1 (List all backup targets) now shows a sub-menu:
  1) View target details
  2) Back to main menu
- Removed old option 6 (View target details) from main menu
- Renumbered options: 7 → 6 (Reinstall), 8 → 7 (Exit)
- Main menu prompt changed from [1-8] to [1-7]
- Sub-menu uses same resolve_target_input() for number/name selection

BENEFITS:
- More intuitive workflow (view list, then optionally drill down)
- Cleaner main menu (7 options instead of 8)
- Reduces redundant listing of targets
- Users can quickly return to main menu without viewing details
