Two bugs found during end-to-end testing:
1. FlowProcessor never restarted flows when config changed — it only
started them once. Stale NATS JetStream data from previous sessions
caused services to bind to wrong topics. Fix: stop and restart flows
on every config push that includes flow definitions.
2. Gateway publishToTopic sent messages without an id property. Pipeline
FlowProcessor handlers check properties.id and silently return if
missing. Fix: auto-generate a message id when publishing to topics.
Both fixes validated: 13/13 integration tests passing, PDF decoder
correctly receives and processes document messages through the pipeline.

Marks FlowProcessor and EmbeddingsService constructors as protected
since these classes should only be instantiated via subclasses.

Fix three critical bugs preventing the NATS message pipeline from working:
- FlowProcessor now subscribes to config-push topic (was missing entirely),
using DeliverPolicy.All to replay config on service restart
- NATS streams use wildcard subjects (tg.flow.>) instead of per-topic
narrow filters that caused 503 errors on publish
- Subscriber dispatch loop has exponential backoff on errors to prevent
tight error loops
Add service runner scripts (gateway, config, LLM) and a 7-test
integration suite that verifies config CRUD, WebSocket round-trip,
and full LLM text-completion through the NATS pipeline.
Fix Docker Compose infra: pin Tempo to v2.6.1, remove deprecated Loki
config fields, add user:0 for volume permissions, remap conflicting
ports (FalkorDB 6380, OTLP 4327/4328).
