Seafile discontinued linux-clients.seafile.com: it resolves but accepts no connections on 80 or 443, and the official docs no longer mention APT at all. Every `docker build` has failed since. Upstream now ships the CLI as an AppImage, so install 9.0.19 from the download site. The AppImage is unpacked rather than executed. Running one needs FUSE and so a privileged container, and its self-extraction also fails when the build host cannot execute the payload's architecture. Unpacking the appended squashfs directly avoids both. Also add the bundled seafile/pysearpc bindings to the venv path. The APT package installed them system-wide, where `venv --system-site-packages` picked them up; dsc imports seafile directly for RPC, not only through seaf-cli, so it broke when that implicit dependency went away. Drops apt-key, pins the version, and verifies a SHA256 before unpacking. Build-time smoke checks assert the seaf-cli subcommands and the app's own imports. Note: the AppImage is x86_64-only, and upstream publishes no digest or signature, so the pinned checksum is trust-on-first-use.
