fix(backup): stop ignoring the configured database-backup destination path

databaseBackupService.getBackupConfig() returns the raw
database_backup_*-prefixed setting keys, but backup() and
startScheduledBackups() destructured unprefixed names off that
object (destinationPath, compress, enabled, schedule,
retentionDays, emailOnSuccess/Failure). None of those keys ever
existed on the config object, so every read silently fell through
to its hardcoded default.

The visible symptom (reported in issue 1365): the inline database
dump that runs before every file backup (default ON) always tried
to create /backup/database, regardless of what an admin configured,
and died with EACCES on the read-only default path — before the
file backup's own (correctly wired) backup_destination_path was
ever reached. The standalone scheduled database-backup runner had
the same bug: config.enabled was always undefined, so it silently
never started regardless of database_backup_enabled.

Also fixes saveManifestToLocal's manifest-directory fallback,
which hardcoded /backup instead of matching the sane
getStoragePath()/backups default used everywhere else for a
missing backup_destination_path.
