Document audit logging tracing ID support (v1.18.0) (#2287)

* Document audit logging tracing ID support (v1.18.0)

Add a "Tracing IDs" subsection to the Audit Logging section of security.md,
and code snippets for all six client SDKs showing how to attach an
x-request-id header to requests so it appears in audit log entries.

* Don't hide imports in Python snippet

+### Tracing IDs
+
+*Available as of v1.18.0*
+
+You can attach a tracing ID to individual requests. When audit logging is enabled, Qdrant includes the tracing ID in the audit log entry, enabling the correlation of client-side operations with their corresponding log entries.
+
+Qdrant reads the tracing ID from the first matching header in the following order: `x-request-id`, `x-tracing-id`, `traceparent`. Tracing IDs longer than 256 characters are truncated.
