Ryan Hughes defbf90e89 Fully revert USB and Thunderbolt device approval (#15091)
* Revert "Merge pull request #11874 from acrogenesis/feature/usb-device-authorization"

This reverts commit 5cb31317b4, reversing
changes made to 9d48fc402e.

* Undo USB and Thunderbolt device approval on machines that ran it

* Verify boot rebuilds, recover Thunderbolt journals and prove USBGuard ownership in the removal migration

* Read the boot partition from ESP_PATH and stop on failed Bolt reads in the removal migration

* Recover Bolt's original mode from the setup journal in the removal migration

# omarchy:summary=Factory-reset this machine back to its freshly-installed state
# omarchy:group=setup
# omarchy:requires-sudo=true
# omarchy:examples=sudo omarchy-system-factory-reset
# Returns the machine to provisioning state — fully installed, no user, first-boot
# setup pending — the state you want before selling or handing the machine on.
#
# The running root (@) is swapped for a fresh writable clone of the @factory
# snapshot, so user-installed packages and /etc drift are gone too. That
# snapshot is taken by the Omarchy Quattro installer, so only machines
# installed from that ISO can be reset; a machine upgraded to Quattro from an
# earlier version has no baseline to return to and is turned away.
#
# The heavy lifting happens on the next boot via omarchy-system-factory-reset-finish, staged
# here. On encrypted installs the LUKS volume is re-keyed to a throwaway
# passphrase with an auto-unlock keyfile for the provisioning window; first-boot setup
# re-keys it to the new owner's password and removes the keyfile. A platform
# whose boot chain the Limine UKI path can't drive rebuilds, verifies and
# unlocks it through omarchy-lifecycle-dispatch.
#
# Honest limitations:
# - On unencrypted disks this is deletion, not forensic erasure. fstrim helps
# on SSDs; use blkdiscard + a reinstall if you need certainty.
# - LUKS re-keying changes passphrases, not the volume key. Freed extents
# remain readable to someone with raw-device access and a valid passphrase.
# Use cryptsetup reencrypt or a reinstall if you need certainty.
