Harden UDP queue metrics InfluxDB writes against overlap and failed resets

[Copilot]

This PR addresses the review-thread feedback on the new UDP queue metrics writer. The main issue was incorrect snapshot/reset behavior when InfluxDB writes failed or overlapped, which could drop counters or start duplicate periodic writers.

• Write completion semantics

  • postUdpQueueMetricsToInfluxDb() now supports separate onSuccess and onComplete callbacks.
  • Metric clearing stays on the success path only.
  • Timer cleanup state is released on both success and failure.

• Timer overlap protection

  • startUdpQueueMetricsTimer() now guards against duplicate initialization.
  • Added an in-flight flag so a slow/unavailable InfluxDB write cannot overlap with the next interval tick.
  • The in-flight guard is also released when pre-write work fails, preventing the writer from stalling.

• Focused test coverage

  • Updated UDP queue metrics tests to exercise promise-based write behavior.
  • Added cases for:
    • onSuccess vs onComplete
    • no reset on failed writes
    • duplicate timer startup
    • overlapping interval suppression
    • recovery after getMetrics() errors

• Minor log cleanup

  • Refactored the Qlik Sense version monitor error log expression to satisfy the formatting feedback without changing behavior.

postUdpQueueMetricsToInfluxDb(
    metrics,
    measurementName,
    () => globals.udpQueueManager.clearMetrics(),
    () => {
        writeInProgress = false;
    },
);
