Linux: add emergency cleanup for stale unmounts

Browse Source 
When normal filesystem unmount fails, the Linux path could stop before cleaning VeraCrypt mapper, loop and FUSE objects. Add an explicit emergency dismount request that is only reached after interactive confirmation.

The recovery path lazy-detaches mounted filesystems, uses deferred dmsetup removal for VeraCrypt mapper devices, detaches loop devices, and keeps normal force/ignoreOpenFiles behavior unchanged.

Når dette er aktivert, undersøker VeraCrypt den dekrypterte virtuelle enheten med blkid -p og monterer oppdagede NTFS-filsystemer med ntfs3 i stedet for standard NTFS-bakgrunnssystem. Hvis NTFS-deteksjonen mislykkes, bruker VeraCrypt vanlig automatisk filsystemvalg. Hvis ntfs3 er utilgjengelig eller blokkert av distribusjonen, kan monteringen mislykkes. Dette valgfrie alternativet kan forhindre at hvile- eller dvalemodus henger seg opp på grunn av frosne FUSE-filsystemer i brukerrom.</entry>
