test: full-stack server integration test

Browse Source 
Drives the whole HTTP API against real Postgres/Redis/MinIO + a mock
upstream: health, remote CRUD, proxy miss/hit, local upload/download,
virtual helm merge, objects, stats, probe. Exercises server + api/v1 +
api/v2 + proxy + virtual engines together.
