Feature: Add Monitor Status Column (Active, Testing, Candidate) to CSV Export Data

[elvisimprsntr]

Description:

Currently, the CSV data exported by the NTP Pool monitoring system does not include the status of each monitor (e.g., whether it is active, testing, or a candidate). This omission makes it difficult for operators and contributors to fully understand how their servers are being scored and which monitors are influencing those scores.

Proposed Enhancement:

• Add a new column to the CSV export that explicitly indicates the monitor’s status:
  • active → monitor is fully participating in scoring
  • testing → monitor is under evaluation but not yet authoritative
  • candidate → monitor is available but not currently used for scoring
• This column should be included alongside existing fields (ts_epoch, ts,offset, step, score, monitor_id, monitor_name, rtt, leap, error) for each monitor entry.

Justification:

• Transparency: Operators can better interpret score fluctuations when they know which monitors are authoritative.
• Debugging: Helps contributors identify anomalies caused by testing or candidate monitors.
• Operational Discipline: Provides a documented, predictable dataset for downstream analysis pipelines (Grafana, custom dashboards, etc.).
• Community Benefit: Encourages trust and collaboration by exposing the same information the system already uses internally.

Impact:

• Minimal technical overhead: the monitoring system already tracks monitor states internally.
• Significant usability improvement for server operators and data analysts.
• Aligns with the project’s ethos of openness and community-driven reliability.
