🔵 Tier A · Mergeable after minor fixes

The interval request and response behavior is untested, so merge confidence is A until that minor test gap is addressed.

This update exposes interval scheduling through function creation and updates, adds interval data to the Function and BillingPlan models, and advances the SDK version headers. The examples and changelog now include the new v7.9.0 options and model fields.

### Issue 1
functions/functions.go:331-333
**Test interval serialization and model decoding**

The existing Functions tests call Create and Update, but their handlers only check the HTTP method, so they would pass if these new options stopped sending `interval`. The new Function response field is also not covered by its model round-trip test; assertions for the request payloads and decoded interval would protect this feature.
