fix: GRUB theme font refs, improve QEMU test script

Theme: remove explicit font name references that don't match
grub-mkfont output names, remove select_*.png pixmap reference
(files don't exist). GRUB falls back to default when theme fails
to load — this was causing the Debian helmet to show.

QEMU test script: add --bios/--nographic flags, serial console
logging to /tmp/archipelago-qemu-serial.log, auto-detect latest
ISO, use -drive for OVMF firmware.
