fix(ti): send a platform TI service specification id to SRM

SRM looks up a required traffic_influence capability requirement on the
activate command's service_specification_id. The app registration id OEG
sent only carries the workload requirement, so SRM rejected every TI.

Add TI_SETTINGS__SERVICE_SPECIFICATION_ID, defaulting to the well-known
id derived from "traffic-influence" (baba6a12-c7b6-507b-9805-5755d38131ee),
following the QoD and Location Retrieval pattern. Send it on activate and
use it as the SRM list filter; the appId filter stays on OEG's own records.
SRM must seed a spec at this id.
