test: satisfy pyright strict annotations on the new supervise RPC tests

Add parameter/return annotations to the fake resolver's propose_supervise /
poll_supervise, annotate the test helpers and the shared _ARGS payload, and
narrow the None-able poll result — no behavior change. pylint 9.83, pyright
clean.
