Issue summary

We would like the ability to define a maximum file size for the upload field. While it's currently possible to achieve this by creating a custom field type, it would be much more convenient if the default upload field supported this functionality out of the box.

We've built several workflows that transfer uploaded files to external resources, and in some cases, these systems impose file size limits. Having built-in validation for maximum file size would help prevent issues and improve user experience.
