Site Pages with Friendly URLs /layoutID Fail Import

A long-standing validation rule that blocked pages whose Friendly URL matched their numerical Layout ID from being successfully imported has been resolved. Previously, exporting a page with a Friendly URL set to its own Layout ID and importing it into a site where a page had the same Layout ID would throw a LayoutFriendlyURLException and fail silently. This fix changes the import validation logic to allow such Friendly URLs when the Layout ID context matches. Teams with existing import/export automation that worked around this error should review their scripts, as the workaround may no longer be needed.
