Pause, resume and stop, as one variant carrying a verb rather than three
near-identical ones - matching the gateway's `PrintControl`, which exists so
there is one method across four vendor implementations instead of three.
Confirmed live on a P1P (2026-10-11), which is also where the two warnings
in the description come from. A stop is a cancel and is not undoable: the
printer reports the cancelled print as FAILED. And `result: "success"` from
the printer means the command was accepted, not that anything changed - all
three verbs answered success while it sat IDLE with nothing to pause - so a
caller that needs to know the state changed has to read telemetry back.
The enum is `pause|resume|stop` and deliberately not `cancel`, even though
`cancel` is Moonraker's word and the Klipper implementation behind this does
send a cancel. A verb only one vendor recognises must not validate on the
wire.
The "no start a print variant" note stays, with its reason corrected:
starting an uploaded file has now been confirmed by hand, so what is missing
is the path around it - nothing uploads a sliced file to a gateway and
nothing decides which printer runs which job.
