v2.3.1 — RAM-mode disable bug fix (id-based BLS targeting)

Fixes a production bug reported by Auke: disable sometimes left
audiophile.overlay=1 in the boot cmdline because grubby --update-kernel=DEFAULT
resolved ambiguously when the recovery entry shares the same kernel path.

The module now reads saved_entry from grubenv (the one authoritative source),
edits the BLS .conf file directly, and verifies the change after every
add/remove. A reboot prompt (default Y) is also offered immediately after
disable — the current session is still on the RAM layer until an actual reboot.

Reported and fixed by Auke.
