bug: [CloudflareStorage] expiry sometimes is 59 which breaks KV API

[firtoz]

Example error:

✘ [ERROR] Error: KV PUT failed: 400 Invalid expiration_ttl of 59. Expiration TTL must be at least 60.

      at async Object.set
  (file:///home/frtn/WORK/2024/llm-ws/node_modules/@openauthjs/openauth/dist/esm/storage/cloudflare.js:12:7)
      at async Object.subject

Seems to be caused by:

  async set(key, value, expiry) {
      await options.namespace.put(joinKey(key), JSON.stringify(value), {
        expirationTtl: expiry ? Math.floor((expiry.getTime() - Date.now()) / 1000) : undefined
      });
    },

and

 function set(adapter, key, value, ttl) {
    const expiry = ttl ? new Date(Date.now() + ttl * 1000) : undefined;
    return adapter.set(encode(key), value, expiry);
  }

put() method

- `expirationTtl` is the number that represents when to expire the key-value pair in seconds from now. The minimum value is 60.
