[SanthoshGujulvajagadeesh]

Reason for change: Handle Security Edge feature for business - Add T2 markers
Test Procedure:

• residential and business devicemode needs to be tested.

Functionality of the following DMLs need to be tested:

Device.DeviceInfo.X_RDKCENTRAL-COM_RFC.Feature.EnableMultiProfileXDNS
Device.X_RDKCENTRAL-COM_XDNS.DNSSecEnable

Above mentioned DML parameters SHOULD work only if the devicemode is business.

Risks: Low
Priority: P1

Pull request overview

Adds a telemetry (T2) marker when DNSSec is attempted in residential mode, supporting the “Security Edge for business-only” behavior by making non-business usage observable via telemetry.

Changes:

• Emit a T2 event when DNSSecEnable is set in residential mode (OneStack builds).
• Move the telemetry header include from cosa_xdns_apis.c into cosa_xdns_apis.h.
