For a database target, the target list showed only its expiry, so the archive file the README's backup and move-away advice depend on could only be found from a shell on the host. Each database target now shows its archive file's name, its size on disk (the file and its -wal together) and when it was last written, relative with the full UTC time on hover, all from the files' metadata without opening the archive. Before the first write, and after the file has been moved away, it shows the name and "not created yet". Tests cover all three states. Model: opus-5-5
