fix(tools): handle all Atlassian error formats in parseJsmErrorMessage (#4088)

Update parseJsmErrorMessage to extract errors from all Atlassian API
response formats: errorMessage (JSM), errorMessages array (Jira),
errors[].title RFC 7807 (Confluence/Forms), field-level errors object,
and message (gateway). Remove redundant prefix wrapping so the raw
error message surfaces cleanly through the extractor.
