…prevention (#7050) Adds helpers_test.go with tests for: - indexOf: 10 tests covering found/not-found/edge cases - replaceAll: 9 tests covering multi-replace and empty inputs - jsonMarshal: 6 tests covering types, no-trailing-newline, errors - writeSSEEvent: 9 tests verifying SSE frame injection prevention Security-relevant: validates that newline/CR stripping in writeSSEEvent prevents SSE frame injection attacks (issue #7050).

Pull request overview
This PR adds unit tests for the pure helper functions in pkg/api/handlers/gitops/helpers.go, including security-relevant coverage for writeSSEEvent’s newline/CR stripping intended to prevent SSE frame injection (referenced in #7050 / #19564).
Changes:
- Add table-driven tests for
indexOf,replaceAll, andjsonMarshaledge cases. - Add security-focused tests for
writeSSEEventformatting and event-name sanitization to prevent SSE injection.
