fix: add serial getty and console activation services to init.d

Boot process now includes:
- 25_serial_getty.service: getty on serial console (visible in QEMU -nographic)
- 29_activate_console.service: inputd -A 2 (activate VT2)
- 30_console.service: getty on VT2 (framebuffer console)

Fixed hunk counts (7→8, 8→9) for correct patch application.
Services use 'oneshot_async' type for fire-and-forget startup.

ZSH is the default shell for all user accounts (base.toml, mini, full, greeter).
