OpenTelemetry trace route does not match standard

[baodrate]

Currently, venator collects traces on the route /v1/trace:

venator/venator-app/src-tauri/src/ingress/mod.rs

Lines 145 to 148 in 311f674

	.route("/tracing/v1", post(self::tracing::post_tracing_handler))
	.route("/v1/logs", post(self::otel::post_otel_logs_handler))
	.route("/v1/metrics", post(self::otel::post_otel_metrics_handler))
	.route("/v1/trace", post(self::otel::post_otel_trace_handler))

But for http/protobuf/http/json, the path should be /v1/traces¹

So users setting OTEL_EXPORTER_OTLP_ENDPOINT to localhost:8362 will not see traces using either protocols, unless they set OTEL_EXPORTER_OTLP_TRACES_ENDPOINT manually (different per proto).
