feat(nodejs): pause and resume jobs from the TypeScript SDK (#4113)

Companion to #4112: `pauseJob` and `resumeJob` on `Connection`, posting
to the server's `/v1/jobs/pause` and `/v1/jobs/resume` endpoints. A
pause parks the job until it is resumed: its workers drain and stop, and
a resume re-queues it to pick work back up from checkpoints.

The outcome strings mirror the server's answers — `"pausing"`,
`"already_paused"`, or `"committing"` (a job finalizing its results
cannot be parked; retry shortly), and `"resumed"`, `"still_pausing"`, or
`"not_paused"` — so a caller can retry the transient refusals rather
than treat them as failures.

Stacked on #4112 (shares the Rust core change); draft until the
server-side endpoints reach production.
