MSATP/Graph API Support

[morgan-nolan-ibm]

Currently, the msatp connector does not support the newer Microsoft Graph Security API endpoint (POST /security/runHuntingQuery) and is instead hard-coded to use the legacy Defender for Endpoint Advanced Hunting API (/api/advancedqueries/run). We need to extend the connector to optionally call the new Graph endpoint under the ThreatHunting.Read.All permission while reusing the existing STIX translation and result-formatting infrastructure.
