Telemetry gRPC ingest breaks UI but still is exposed

[golyalpha]

Describe the bug
When ingesting telemetry (on OneUptime Open Source) via the gRPC endpoint of the cluster-internal service, UIs that handle traces tend to break (page goes white and a bad route exception is logged - it seems things like trace IDs are sent to the frontend as bytes, rather than hex-encoded strings)

Tested with Python instrumentation, exporter version 1.39.1

To Reproduce
Steps to reproduce the behavior:

1. Send traces to OneUptime's Telemetry service via the gRPC endpoint
2. Try to open traces view, open log details, or set up a traces monitor
3. After trace data loads the page goes blank

Expected behavior
Either:
Traces from the gRPC endpoint should be transformed so the UI can handle them correctly
The gRPC endpoint should probably not be exposed at all - even via the cluster-internal service.
