LCORE-1802: Add OpenTelemetry environment variables to docker-compose

[anik120]

Description

Add OpenTelemetry OTLP exporter configuration environment variables to docker-compose files with safe defaults that keep tracing disabled until explicitly enabled.

Variables added use ${VAR_NAME:-default} pattern for flexible configuration:

1. OTEL_EXPORTER_OTLP_ENDPOINT - OTLP collector endpoint URL (default: empty)
2. OTEL_EXPORTER_OTLP_PROTOCOL - Export protocol, e.g. http/protobuf or grpc (default: empty)
3. OTEL_SERVICE_NAME - Service identifier in traces (default: empty)
4. OTEL_SDK_DISABLED - Enable/disable tracing (default: true - tracing OFF)

Timestamp: 2026-05-20T08:09:30.641Z
Learning: In Llama-stack config YAMLs, when defining a Llama Guard safety shield entry, set `provider_shield_id` to the *guard model identifier* (e.g., `meta-llama/Llama-Guard-3-8B`). Do not use a chat/generative model id (e.g., `openai/gpt-4o-mini`): a chat-model id (or `native_override`) indicates only an override landed and does **not** mean the safety shield is actually gating queries. Ensure any E2E coverage for the related implementation (JIRA/E2E tests) exercises a real Llama Guard model to verify that the shield is effective.
