scripts: migrate all QEMU/test scripts to single system image

boot.sh: replace esp/ + DISK_IMG with single SYSTEM_IMG on ide.0
(hooks into mksystem.sh --force for auto-staging).

boot-image.sh: delegate to mksystem.sh --chain (build-image.sh deleted).

build-image-release.sh: delegate to mksystem.sh --chain --gpt.

qemu.sh: flexible launcher uses SYSTEM_IMG; --chain flag for
full-chain build.

test-disk.sh: drop ESP_DIR (mksystem.sh stages everything).

test-fault.sh: boot system.img on ide.0 + CRASHLOG stick on ide.1;
replace deleted mkdisk.sh with inline mkfs.fat.

test-gfx.sh: system.img on ide.0, stage via mksystem.sh.

test-mouse.sh: system.img on ide.0, stage via mksystem.sh.

test-msg.sh: system.img on ide.0, stage via mksystem.sh.

Makefile: remove stale build-image.sh/mkdisk.sh references from help;
image target delegates to mksystem.sh --chain.

All scripts syntax-checked (bash -n). build-image.sh and mkdisk.sh
no longer referenced anywhere.
