App, AsyncSSH: Allow unused "type: ignore" comments

Some '# type: ignore' comments are needed because they complain about missing
but optional third-party packages: argcomplete, paramiko, asyncssh. The next
commit will enable warn_unused_ignores, and since nor mypy nor pyright have a
way of knowing that this is a tolerable lack of packages, this commit teaches
them in advance.
