BirthDataSource and ArrivalDataSource concatenated a data-controlled column value (the gender lookup display value and the sourceFacility value, respectively) directly into the clinical-history HTML string without escaping. That string is serialized to the history row's html property and rendered unescaped in the EHR client, so a crafted value persisted and executed as stored XSS when a user viewed the animal's clinical history. Both now route the value through the base class safeAppend helper, which HTML-escapes via PageFlowUtil.filter, matching every other nirc_ehr data source. The redundant manual hasColumn/null guards and the now-unused FieldKey import were dropped.
