The CPIO-embedded initrd approach failed (too large for iPXE memory).
Instead, use iPXE's sanhook to connect the ISO as a SAN block device
before booting with kernel/initrd. The installer finds the ISO on the
SAN device while we retain control over kernel parameters.

Instead of sanboot (which can't pass kernel params for automation),
switch back to kernel/initrd boot. The ISO is embedded in the initrd
as a CPIO append. A pxe-init wrapper script loop-mounts the ISO
before handing off to the original init, so the installer finds it
as a block device. Uses rdinit=/pxe-init kernel parameter.

Proxmox has no kernel parameter for HTTP ISO fetch. Instead, use
iPXE's sanboot command to present the ISO as a virtual CD over HTTP.
The installer finds it as a block device and boots normally.

The Proxmox installer needs the full ISO to access packages and
installer data. Previously the ISO was deleted after extracting
kernel+initrd. Now we keep it as original.iso and serve it via HTTP.
The iPXE script passes proxmox-iso-url=<url> so the installer
fetches the ISO over the network instead of scanning block devices.

iPXE needs --name on the initrd command and initrd=<name> on the
kernel line to properly pass the initrd to the kernel. Without this,
the kernel never receives the initrd, causing VFS mount failure.

The Proxmox initrd is too large for the default ramdisk allocation,
causing VFS to fail mounting root. Add ramdisk_size=16777216 (16GB)
along with rw, quiet, and splash=verbose for proper installer boot.

Upload Proxmox ISOs via API or dashboard UI, extract kernel+initrd
using pure-Go iso9660 library, store on disk, and serve over HTTP
for PXE booting. Dynamic kernel/initrd filenames per image replace
the previous hardcoded paths.
