Networks and Sites: Ensure fileupload_maxk is an int to avoid potential fatal errors.

Browse Source 
This changeset fixes a potential fatal error, for example when "Max upload file size" setting is set to an empty value. It also adds unit tests for `upload_size_limit_filter`.

Props mjkhajeh, bhrugesh12, SergeyBiryukov, kebbet, audrasjb, felipeelia.
Fixes #55926.
