* Replace the secret cookies are signed with, and end every session there is.

* out **now**: a cookie whose session is gone identifies nothing, so the next request from every
* browser — on every instance, since the rows are shared — starts a new, anonymous one. Rotating
* the secret is what makes the cookies themselves worthless, and that one waits: @fastify/session
* and @fastify/cookie are handed the secret when the HTTP server starts (`index.ts`), so this
* server goes on validating signatures with the old one until it is restarted.
*
* The API key keypair is untouched: it carries its own passphrase (`models/apiKeys.ts`), so keys
* already issued keep working.
*
* @returns How many sessions were ended, or null if the settings failed to save
