teknium1 b4873a5de7 fix(setup): Escape skips instead of exiting, add control hints to all prompts ...

Previously pressing Escape in any setup wizard menu called sys.exit(1),
killing the entire wizard with no way to recover. Now:

- prompt_choice: Escape keeps the current default and moves on (prints
  'Skipped (keeping current)'). Shows '↑/↓ Navigate  Enter Select
  Esc Skip  Ctrl+C Exit' hint.
- prompt_checklist: Escape returns pre-selected items instead of empty
  list. Shows 'SPACE Toggle  ENTER Confirm  ESC Skip  Ctrl+C Exit'.
- prompt_yes_no: now catches KeyboardInterrupt/EOFError properly.
- Fallback number prompts also show control hints.

Ctrl+C still exits the wizard cleanly.
