# T-252: Fix unresolved C-XXX/F-XXX IDs in filtered fabric graph

## Context

When filtering the fabric dependency graph by subsystem, cross-subsystem dependency targets showed as raw IDs (C-008, F-001) with "unknown" type instead of resolved names. Bug: `fabric_graph()` passed the filtered component list as `all_components` to `_build_graph`, so the `id_to_name` map only contained same-subsystem components.

## Acceptance Criteria

### Agent
- [x] Filtered graph resolves cross-subsystem C-XXX/F-XXX IDs to component names
- [x] Dependency target nodes show correct type and subsystem grouping

## Verification

# Audit-filtered graph has no unknown-type nodes
curl -s "http://localhost:3000/fabric/graph?subsystem=audit" | grep -q "learnings-data"
curl -s "http://localhost:3000/fabric/graph?subsystem=audit" | grep -q "checkpoint"
