Bulk CMS authoring improvements and locale parameter updates

Bulk CMS authoringData API v2

We’ve enhanced the create collection items endpoint to support bulk creation. Now you can create multiple CMS items in a single request by passing an array of items to the items property. This provides a more efficient way to create multiple items while maintaining compatibility with the existing bulk Create Items endpoint.

Introducing the `localeId` ParameterData API v2 Data API v2 - Beta

We’re standardizing our query parameter naming by introducing localeId as the preferred parameter name, replacing locale. For backward compatibility, the locale parameter will continue to work, but we recommend using localeId in all new implementations. This change affects the following endpoints:

List form submissions by site

List form submissions by site - A new endpoint that lets you retrieve form submissions across your entire site. Unlike the existing List Form Submissions endpoint, this endpoint:

Takes siteId as a path parameter
Accepts elementId as a query parameter to filter by formElementId
Works seamlessly with forms in components, where each component instance gets a unique formId but shares the same formElementId

To use this endpoint, first get the formElementId from the List Forms API, then pass both the siteId and formElementId to retrieve all submissions for a specific form, even when it appears in multiple component instances.
