P2 Badge Restore the immutable creation date

For this existing detection, changing creation_date from 2023-04-11 to 2023-02-11 corrupts its historical metadata. The EventBasedDetection schema explicitly defines this field as the object's original creation date and says it should never be updated (schemas/EventBasedDetection.schema.json:6841-6845), so retain the prior value and use modification_date for this change.

P1 Badge Close the unterminated SPL string literal

The added "something_new value has no closing quote, so Splunk cannot parse this production detection when it is deployed or executed. As a result, the search will fail instead of evaluating 3CX indicators; close the string before the closing parenthesis.
