Add Prometheus metrics to the boundary log proxy for observability: - batches_dropped_total (reason: buffer_full, forward_failed) - logs_dropped_total (reason: buffer_full, forward_failed, boundary_channel_full, boundary_batch_full) - batches_forwarded_total Also add BoundaryStatus to the BoundaryMessage envelope so boundary can report dropped log counts as a separate wire message. The agent records these as Prometheus metrics, making boundary-side data loss visible. Backwards compatibility for older versions of boundary is maintained.
