Stop always calls systemctl and treats exit 5 (unit already collected)
as done, so there is no is-active/stop race. Cleanup never masks the
copy error, the play ssh timeout covers the remote worst case, and
tests cover stop exit codes and systemd-run stderr reporting.

- Stop is a no-op when the collected player unit is already gone
(raw systemctl stop exits 5 on the Frame; verified 2026-09-29).
- Surface systemd-run stderr when the player can't start.
- Keep the copy error if the cleanup ssh also fails; reject upload
names that the play path can never accept.
- Allow 60 s for play (ffprobe 30 s + systemd-run 15 s remote).
- Docs: four-hour cap is unconditional; no delete action yet; fix a
garbled timing sentence.
