The trackers list page on the cookie-banner configuration screen needs
to filter rows by the third party that the pattern resolves to. The
tricky part is that "third party" comes from two unrelated tables:
ThirdParty (org-scoped, linked through tracker_patterns.third_party_id)
and CommonThirdParty (global catalog, reached indirectly through
common_tracker_patterns.common_third_party_id). The filter must accept
either flavour of GID and resolve transparently.
Add a single thirdPartyId field to TrackerPatternFilter and dispatch
on the GID's entity-type prefix at the resolver:
ThirdPartyEntityType -> WithThirdPartyID
CommonThirdPartyEntityType -> resolve common_tracker_pattern_id list
via the cookiebanner service, then
WithCommonTrackerPatternIDs
Any other entity type returns an Invalid error rather than silently
matching everything; an unknown caller-supplied GID is a contract bug.
The empty-but-non-nil ID slice produced when a CommonThirdParty has no
patterns yet correctly yields zero rows because the SQL fragment uses
ANY(...).
To populate the filter combobox, add a new CookieBanner.linkedThirdParties
field returning [TrackerPatternThirdPartyLink!]!, a union of ThirdParty
and CommonThirdParty. The resolver collects DISTINCT third_party_id and
common_tracker_pattern_id from the banner's tracker patterns (no joins,
per coredata convention), then chains the catalog lookup through
CommonTrackerPatterns -> CommonThirdParties. Authorization scopes
follow the existing trackerPattern resolvers: ActionTrackerPatternList
gates the aggregation, ActionThirdPartyGet and ActionCommonThirdPartyGet
each gate their respective fan-out only when that branch has work.
The org-scoped fan-out uses dataloadgen.LoadAll so it batches in a
single round-trip; per-key NotFound errors are dropped (a deleted
third party doesn't fail the whole list), other errors bubble up.
