feat(mcp): add fullWidth parameter to create_document and update_document tools (#12338)

The fullWidth field is already persisted on the Document model and
supported in the REST API schemas (DocumentsCreateSchema, DocumentsUpdateSchema),
but the built-in MCP server did not expose it.

This patch adds fullWidth as an optional boolean parameter to both
create_document and update_document MCP tools, passing it through to
documentCreator and documentUpdater respectively.
