fix(embed): conformance mock + TypeScript router vs the real Monad API [PRO-455]

[Credgate]

Review of the Go router (#15) surfaced defects the TypeScript reference has too — and the conformance mock could not have caught any of them. It returned every row regardless of limit, and had no GET /v1/{org}/{kind}s/{id} route at all, so CI was green on a bug that bites the eleventh pipeline.

First of three stacked fix PRs (PRO-455 → PRO-456 → PRO-457), one per router. Every claim was validated against the API source in monad-inc/api, not the published spec — sdk/openapi.json is ~15 months stale.

Linear: PRO-455

The mock now reproduces the real API

• pages every list at Monad's default limit of 10, with no maximum (api/pkg/routes/v2/routes/pipelines.go:727)
• serves the connector detail route with component_of, pinned to the same narrow projection the datastore actually emits — no status, no nodes (core/pkg/datastore/postgres/pipelines.go:292). A too-generous mock here would let a router pass locally and fail live.
• accepts type on output create, output_type staying a deprecated alias
• tracks connectors statefully so a delete is observable

test_status_resolves_past_the_first_page_of_pipelines is the gate: it fails against the pre-fix routers and passes after.

TypeScript router

The same six fixes that follow for Go and Python, so the three stay identical on the wire. Detail is in the commit message; the two that matter:

• pipeline resolution moves to component_of — the old scan sent no limit, so past a tenant's tenth pipeline it reported "not connected" for pipelines that exist
• setEnabled PATCHes {enabled} alone. PATCH became a true partial update in api#2163; the read-modify-write it replaces rebuilt the graph from a partial field list, silently dropping node config_overrides and edge schema_detection_spec on every toggle.

Reviewer note

One behavior change worth a look: an unknown connector id now returns 404 not_found instead of 200 {hasPipeline:false}, since resolution goes through a connector fetch. test_ingress_lifecycle asserts the new shape after removal.

Verification

pnpm test 13/13, conformance ROUTER=ts 35/35 (ROUTER=go and ROUTER=python also green on this mock, unchanged).
