Wire shared EventDeduplicator across all ingestion paths (JSONL tailer,
OTLP/gRPC receiver, OTLP/HTTP receiver) so duplicate events from dual
ingestion are silently dropped on (session_id, worker_id, sequence).
Also adds docs/needle-exporter-wiring.md (OTLP configuration guide for
NEEDLE), SpanDag React component, EventFilter.eventType field, and
various test/layout fixes.

Add full OTLP/gRPC receiver terminating LogsService, TraceService, and
MetricsService Export RPCs. Decoded protobuf records are normalized via
the shared Normalizer pipeline and emitted as LogEvents on the event bus.
- gRPC server via @grpc/grpc-js with protobufjs codec
- Protobuf definitions for all three OTLP collector services
- enrichRecord() merges scope/resource attributes for normalizer
- extractDataPoints() handles gauge, sum, and histogram metrics
- Integration tests with real gRPC client/server round-trip
