Opening moved `.transcribee` file open transcript, but has no media file.

When opening (using recent document) a `.transcribee` file that was removed, the transcript loads, but then media does not play, because `could not open archive file '....'`.

Reproduce the issue by opening a removed .transcribee file from recent documents, then trace the handling of the missing archive after the transcript loads. Confirm the expected behavior for absent media and verify that opening the transcript no longer produces an unusable media playback state.
