fix(tracker-api): wire CoreApi:BaseUrl direct to Core /api/v1 (LV-18 config residual)

[beyondnetPeru]

What

Fixes the committed CoreApi:BaseUrl in the tracker-api BFF, which pointed at the tracker-gateway's imaginary /api/core/api/v1 prefix. With that value the tracker-api → gateway → Core evaluation hop 404s: the client posts to /api/core/api/v1/evaluate, which falls to the gateway's @All('*') catch-all.

Why this topology (decision)

The hop is wired direct to the Core's /api/v1 surface — the intended topology, already decided and documented:

• ADR T-038 — the tracker-api BFF is the satellite's sole Core client; it calls /api/v1 directly, never through the gateway.
• ADR T-052 / gap LV-18 — the /api/core prefix is the gateway's aggregation facade for external consumers; it does not exist on the Core pod ("the /api/core prefix is imaginary… the real base is /api/v1 directly").
• Every other config already agrees: the code default (CoreEvaluationOptions.cs), evolith.satellite.json, all Helm values*.yaml, docker-compose.fullstack.yml, and the live-test defaults.

This is a sibling residual of gap LV-18, whose earlier closure rebound the MCP tools to the BFF but never corrected the BFF's own Core-client default. It stayed hidden because compose/Helm mask it via a CoreApi__BaseUrl env override — only a run against the committed config hit the bug.

Change

BaseUrl: http://localhost:4000/api/core/api/v1 → http://localhost:3001/api/v1 (compose Core host port), with the topology documented inline.

Verification (e2e against the running full stack)

Request	HTTP	Meaning
POST :5100/api/v1/core/evaluate (tracker-api BFF)	200, provenance=core, coreEndpoint=/api/v1/evaluate	direct hop works, real Core verdict
POST :4000/api/core/api/v1/evaluate (old value)	404	the bug reproduced
POST :3001/api/core/evaluate (on the Core)	404	/api/core is imaginary on the Core
