v0.5.7: skip PNG boot-menu background on legacy BIOS clients

The menu emitted `console --picture … || console`, relying on the
trailing `|| console` to recover on iPXE builds without IMAGE_PNG +
CONSOLE_FRAMEBUFFER. On legacy BIOS (`undionly.kpxe`, no PNG) the
`--picture` attempt misbehaves before the fallback can recover — it
tries to set a framebuffer mode the BIOS console can't honour — so the
boot menu fails to render on BIOS clients.

Fix: gate the command on `iseq ${platform} efi`, so BIOS (`pcbios`)
clients never issue `console --picture` at all and drop straight to the
plain text menu, while UEFI clients still get the graphical background.
This is automatic and per-client — a mixed BIOS+UEFI fleet each gets the
right treatment with no operator toggle. A PNG-less UEFI build (upstream
i386-efi) still falls back gracefully through the same `|| console`.

Menu snapshot updated to match. 254 tests pass, clippy clean.
