When playing with long fbwhiptail/whiptail messages, this commit played around the long string using fold.

Which gave the exact output of what will be inside of the fbwhiptail prompt, fixed to 70 chars width:
'''
This will replace the encrypted container content and its LUKS Disk
Recovery Key.
The passphrase associated with this key will be asked from the user
under the following conditions:
1-Every boot if no Disk Unlock Key was added to the TPM
2-If the TPM fails (hardware failure)
3-If the firmware has been tampered with/modified by the user
This process requires you to type the current LUKS Disk Recovery Key
passphrase and will delete the LUKS TPM Disk Unlock Key slot, if set
up, by setting a default boot LUKS key slot (1) if present.
At the next prompt, you may be asked to select which file corresponds
to the LUKS device container.
Hit Enter to continue.

Therefore, for long prompts in the future, one can just deal with "\n 1-" alignments to be respected in prompts and have fold deal with cutting the length of strings properly.

Rationale:
cpio -t alone cannot extract initrd past early cpio (microcode) in most packed initrd.
unpack_initramfs.sh already under master comes to the rescue, but its usage up to today was limited to pass firmware blobs to final OS under boards/librem_mini_v2
Debian OSes (and probably others) need to have cryptroot/crypttab overriden directly, otherwise generic generation of crypttab is not enough.
Extracting crypttab and overriding directly what is desired by final OS and exposed into /boot/initrd is the way to go otherwise hacking on top of hacks.
This brings default packed modules under Heads to 5 modules, which needs to be deactivate in board configs if undesired:
user@heads-tests-deb12:~/heads$ grep -Rn "?= y" modules/ | grep -v MUSL
modules/zlib:1:CONFIG_ZLIB ?= y
modules/zstd:3:CONFIG_ZSTD ?= y
modules/exfatprogs:2:CONFIG_EXFATPROGS ?= y
modules/busybox:2:CONFIG_BUSYBOX ?= y
modules/e2fsprogs:2:CONFIG_E2FSPROGS ?= y
Debian 12's initrd by default now consists of an uncompressed cpio
archive containing microcode, followed by a zstd-compressed cpio
archive. inject_firmware.sh only supported gzip-compressed cpio, so it
could not extract /init from this archive.
Add zstd-decompress to decompress zstd streams (uncompressed size is
about 180 KB).
Add unpack_initramfs.sh which is able to decompress uncompressed, gzip,
or zstd archives, with multiple segments, much like the Linux kernel
itself does.
Use unpack_initramfs.sh to extract /init for blob jail.
Don't compress the new archive segment containing firmware and the
updated /init.
