Pull request overview

This pull request adds support for OpenTelemetry trace IDs in the TraceIndexTable by introducing a polymorphic encoding/decoding mechanism that handles both Pinpoint and OpenTelemetry server trace IDs.

Changes:

• Introduced type-based encoding/decoding for ServerTraceId to support both PinpointServerTraceId and OtelServerTraceId
• Renamed field from transactionId to serverTraceId in TraceIndexValue.Meta record for better clarity
• Added comprehensive tests for both Pinpoint and OpenTelemetry trace ID encoding/decoding
