fix: update GRUB2 module partition size checks 131072 -> 65536

Browse Source 
After reducing ESP partition from 64MB to 32MB to match Ventoy, the
GRUB2 module's hardcoded partition size checks now reject the disk
with error 7 'Disk partition layout check failed.'

Updated 4 hardcoded 131072 / 67108864 (64MB) values to 65536 / 33554432
(32MB) in:
- src/grub2/hiperiso_cmd.c (3 places in hiperiso_check_official_device)
- src/grub2/hiperiso_def.h (HISO_CMD_CHECK macro partition size)

GRUB2 module rebuilt with new BOOTX64.EFI. Payload rebuilt.
