fix: align telemetry client payload and dimensions with backend schema

Restructure the TelemetryClient to send the correct backend envelope
format ({app, schemaVersion, installId, events: [{name, occurredAt, dimensions}]})
instead of the old per-event format. Update all event dimension names
to match the backend registry (agent_role, adapter_type, error_code, etc.).
