Subject: [PATCH] fix(client): Serialize properly escape characters (#4335)

* Card ID: CCT-1065

Backslashes in regex patterns were not properly escaped, causing
inconsistencies between Fedora 40 and CentOS Stream 9 environments. This
commit ensures that all escape characters are properly serialized.
