A test that sends the reader's property lists, the reads the app makes for a user and for an administrator, and a send, each with the `using` the app builds, to a real, empty Stalwart. Skipped unless STALWART_COMPAT_URL is set; a new CI job sets it once per supported version, from images pinned by digest. The probe that cleared Stalwart 1.0 kept its own copy of the requests and missed List-Unsubscribe:asText; this test fails on that with the server's own error, and passes on both versions with it fixed.
