fix: correct CaptureIntegrationSpecificIdsV2 feature flag key to match server

The server sends the V2 feature flag as `captureIntegrationSpecificIds.V2`
(with a dot), but the SDK was looking up `captureIntegrationSpecificIdsV2`
(no dot). This caused the V2 value to silently fall back to 'none',
preventing IntegrationCapture from initializing for customers whose
legacy V1 flag is set to False.
