Fix unit tests for connection close telemetry

Update test files to match new telemetry interface changes:
- Add latencyMs parameter to all emitConnectionOpen() test calls
- Add missing DriverConfiguration fields in test mocks (osArch,
  runtimeVendor, localeName, charSetEncoding, authType, processName)

This fixes TypeScript compilation errors introduced by the connection
close telemetry implementation.
