Describe the WHOOP disconnect in the contract

The eighth teardown endpoint, missed when the seven siblings were split across
the earlier batches. It has no per-user unsubscribe to make — WHOOP webhook
subscriptions are registered once per developer app rather than per category
the way Withings does it — and it leaves the BYO-key credentials in place so a
reconnect does not force a re-paste.

Like every other `POST /api/<provider>/disconnect`, a repeat call answers 404
rather than an idempotent 200, and the description says so. That completes the
tally: all seven disconnect endpoints refuse a repeat, all six credential
DELETEs accept one.
