feat(otel): enhance telemetry data with session and workflow details

[SyedZawwarAhmed]

📝 Description

Enhances OpenTelemetry (OTel) telemetry data with comprehensive session and workflow tracking details. This update adds new attributes to spans and structured logs across conversation handling, agent process tracking, and component execution to improve observability and debugging capabilities.

Key additions:

• Session tracking: session.id, agent.debug, agent.isTest, agent.domain, log.tags
• Workflow tracking: workflow.id, workflow.step, input.action, input.status
• Component source tracking: source.id, source.name
• Attribute standardization: Converted legacy attribute names to OTel-style format (e.g., agentId → agent.id, processId → process.id)

These enhancements enable better filtering and querying in ClickHouse for debug sessions, test domains, and workflow execution traces.
