test: added unit tests for period (pe) filter functionality in getIfr…

…ameSrc

- Added tests to validate the behavior of the period (pe) filter with single and multiple values. - Ensured proper handling when both pe and ou filters are applied together. - Included a test to confirm pe filter is omitted when empty. - Verified the generated iframeSrc matches the expected URL for all scenarios.
