os.ReadFile on the ISO was OOM-killing the container. Switch to 8MB
chunked reads with overlap to handle matches spanning chunk boundaries.

The modified config was 75 bytes larger than the original (5798 vs 5723),
causing the in-place write to be rejected. Strip comment lines and trailing
whitespace to reclaim space for the added auto-installer kernel parameters.

Two fixes: (1) Search entire ISO for grub.cfg content instead of only at
2048-byte sector boundaries — catches the copy inside the EFI boot
partition image that UEFI firmware actually reads. (2) Match kernel lines
by GRUB 'linux' command prefix instead of requiring '/boot/linux' path.
Added detailed logging of original and modified grub.cfg content.

Modifies uploaded ISO's GRUB config in-place to set timeout=0 and inject
proxmox-start-auto-installer + answer-url kernel params, enabling fully
hands-off installation. Adds /api/boot/auto-answer endpoint that identifies
hosts by ARP-resolving the requester's IP to MAC address.
