Improved alignment options for Initials

The alignment parameter for Initials now supports vertical prefixes, allowing positioning relative to either the top or bottom of the page. This makes it easier to manage initials on documents with varying page sizes.

In the POST and PATCH document endpoints, the alignment parameter now supports the following values: top-left, top-center, top-right, bottom-left, bottom-center, and bottom-right.

For more details, see the Initials Guide.
