feat: Add basic telemetry to event, batch and OTLP endpoints

[MikeGoldsmith]

Which problem is this PR solving?

We don't currently have any logging or telemetry for our endpoints that receive data (spans & logs). This PR adds tracing to the following endpoints using OTel instrumentation libraries. It also configures husky to set appropriate validation error attributes.

Endpoints:

• /event
• /batch
• OTel trace (http & OTLP)
• OTel logs (http & OTLP)

Closes the following issue:

• Closes Refinery returns GRPC errors, but doesn't log them #1054

Short description of the changes

• Configure husky's telemetry callback to set validation attributes on existing spans
• Inject the already configured OTel Tracer into the Router
• Add otelhttp & otelgrpc instrumentation libraries and wire up
• Update tests to set a NoopTracer in the router

Example HTTP span

Example gRPC span

Seems useful. Are there any more attributes you want to add to the spans so we know more about them?
