webhooks
one webhook per key: we post your events to your url, batched once a second, signed when you set a secret. events are batched once a second and posted to your url as {"events":[...]}, with x-tallgrass-name and, when you gave a secret, x-tallgrass-signature: sha256=<hmac of the body>. a failed post is retried three times with backoff (2 s, 8 s, 32 s); after a day of nothing but failure the hook is paused. types keeps it to the events you name; test:true pings first with {"ping":true,"at"}, signed like a batch.
