refactor(graph): absorb Cartographer into graph-api + wire Graph Indexer

Browse Source 
- Wire Graph Indexer library + Persistence into graph-api (csproj refs + DI)
- Add build/overlay endpoints matching Scheduler HTTP contracts
  (POST/GET /api/graphs/builds, POST/GET /api/graphs/overlays)
- Add PostgresGraphRepository for reading from graph.graph_nodes/edges
- Register SBOM ingest, analytics, change-stream, and inspector pipelines
- Comment out Cartographer container in compose (empty shell, Slot 21)
- Add cartographer.stella-ops.local as backwards-compat alias on graph-api
- Update Scheduler config to target graph.stella-ops.local
- Update services-matrix.env, hosts file, port-registry, module-matrix
- Update component-map, architecture docs, Scanner/Graph READMEs
- Eliminates 1 container (stellaops-cartographer)

All 133 existing tests pass (77 Api + 37 Indexer + 19 Core).

## 2) Pipelines
1. **Ingestion:** Cartographer/SBOM Service emit SBOM snapshots (`sbom_snapshot` events) captured by the Graph Indexer. Ledger lineage references become `SBOM_VERSION_OF` + `SBOM_LINEAGE_*` edges. Advisories/VEX from Concelier/Excititor generate edge updates, policy runs attach overlay metadata.
1. **Ingestion:** SBOM Service emits SBOM snapshots (`sbom_snapshot` events) captured by the Graph Indexer (now hosted inside graph-api; Cartographer merged). Ledger lineage references become `SBOM_VERSION_OF` + `SBOM_LINEAGE_*` edges. Advisories/VEX from Concelier/Excititor generate edge updates, policy runs attach overlay metadata.
2. **ETL:** Normalises nodes/edges into canonical IDs, deduplicates, enforces tenant partitions, and writes to the graph store (planned: Neo4j-compatible or PostgreSQL adjacency lists).
3. **Overlay computation:** Batch workers build materialised views for frequently used queries (impact lists, saved queries, policy overlays) and store as immutable blobs for Offline Kit exports.
4. **Diffing:** `graph_diff` jobs compare two snapshots (e.g., pre/post deploy) and generate signed diff manifests for UI/CLI consumption.
