Subject: [PATCH] fix: count checksum-corrupted media as missing on local
 backup import

Import result missingMediaCount compared restored assets against the
backup's declared media file list, so an embedded file that failed
sha256 verification was still treated as present. Compute it from the
actually restored files instead.
