fix: Enable disabling OTEL

[frac]

Problem:
When the otel collector is off the output of it goes into the console out. This makes harder to debug other parts as it is very noisy

Solution
This pull request introduces a mechanism to conditionally disable OpenTelemetry (OTel) instrumentation based on an environment variable. The main change is the addition of a utility function that disables OTel features if requested, and its invocation at application startup.

OpenTelemetry disablement:

• Added a new function disableOtelIfRequested in src/lib/otel.ts that disables tracing, metrics, and diagnostic logging when the OTEL_DISABLED environment variable is set to "true" or "1".
• Invoked disableOtelIfRequested at the top of src/index.ts to ensure OTel is disabled before the server starts, if requested.
