feat(data-access): add yearly job interval (#1380)

## Summary

- Adds `YEARLY: 'yearly'` to the `JOB_INTERVALS` enum in the
Configuration model
- Needed to support yearly-cadence audit types (e.g.,
`commerce-product-enrichments-yearly` for full sitemap-based product
page discovery)

## Related

- [Story: AGENTCOM-388](https://jira.corp.adobe.com/browse/AGENTCOM-388)

## Test plan

- No test changes required — existing tests validate interval logic
generically using `'weekly'`/`'daily'`/`'monthly'` and test the error
path with `'invalid-interval'`
