subhobhai943andClaude Opus 4.8 c982d6b538 feat(auth): Boot-time login prompt; fix(configure): arch selection via dialog
Login:
- Add console_login() (security/auth.c): an interactive boot-time username /
  password gate rendered on the framebuffer console before any session starts.
  It blocks until valid credentials are entered, masks the password, scrubs it
  from the stack, and sets the current user. Default account is SUB / SUB, shown
  as a hint. Wired into the boot handoff in kernel/main.c ahead of both the GUI
  desktop and the emergency TTY shell.

Configure:
- scripts/kconfig/menuconfig.py: fix the architecture (and optimization) picker.
  The lxdialog front-end used --radiolist, where <Enter> confirms the ORIGINAL
  choice and only <Space> moves the dot -- so highlighting a new architecture
  and pressing <Enter> appeared to do nothing. Single-choice groups now use
  --menu (with --default-item), where <Enter> selects the highlighted row
  directly. Also stop the unconditional save-on-exit from overriding an explicit
  "No" at the exit confirmation.

Verified: SUB/SUB logs in (injected via QEMU monitor) -> "Login successful" ->
desktop starts; the desktop stays blocked until login. dialog --menu selection
of aarch64 persists to .config/autoconf.h and retargets `make`. Clean build on
x86_64/aarch64/armv8i.
