Refactors the encryption mechanism to use a flexible LVM-on-a-loop-device backend instead of a fixed-size file. This resolves issues with containers running out of space. - Implements auto-resizing of the container when a backup fails due to lack of space. - Implements transparent inspection of encrypted containers, allowing the UI to display their contents (full/incremental backups) just like unencrypted ones. - Fixes deletion of encrypted backups by ensuring the container is unlocked before deletion. - Fixes a bug where deleting unencrypted user backups incorrectly required root privileges. - Fixes a UI freeze caused by calling a password dialog from a non-UI thread during deletion. - Simplifies the UI by removing the now-obsolete "Show Encrypted Backups" button. - Changes the default directory for encrypted user backups to `user_encrypt`.
