Optimize file size check using quarantine dir and add EE-specific check

Previously, the file size check required a complete graph walk,
which was slow.
This change optimizes the process by using an existing method
that checks only the quarantine directory, improving performance.

Additionally, since this is an EE feature,
a new EE-specific FileSizeCheck class was introduced
to retrieve and apply the push rule file size limit
