Each tracker pattern carries either a direct org-scoped third_party_id
or an indirect link via common_tracker_pattern_id, but the console API
never surfaced either. Expose two optional resolver-driven fields on
the GraphQL TrackerPattern node:
thirdParty: ThirdParty
commonThirdParty: CommonThirdParty
The org-scoped ThirdParty takes priority. When ThirdPartyID is set the
commonThirdParty resolver short-circuits to nil, so the chained
common_tracker_pattern -> common_third_party lookup is only paid for
when a pattern has not been promoted to a tenant-managed third party.
To make the resolver pattern viable across paginated banner trackers
listings, the model now uses @goModel and a custom struct that carries
the foreign-key handles (ThirdPartyID, CommonTrackerPatternID) without
exposing them in the schema. NewTrackerPatternNode populates them from
coredata.
Two new request-scoped dataloaders (CommonTrackerPattern,
CommonThirdParty) batch the chained lookup, mirroring the existing
ThirdParty / CookieCategory loaders. The console mux now wires the
third-party service through dataloader.NewMiddleware so the second
loader has its backing service.
Authorization follows existing precedent: ActionThirdPartyGet for the
org-scoped lookup, ActionCommonThirdPartyGet (granted by the
identity-scoped CommonThirdPartyCatalogPolicy) for the catalog lookup.
ErrResourceNotFound and dataloadgen.ErrNotFound are mapped to a null
field rather than an error.
