  observability: retire the dead Nagios monitoring path, migrate balance signals to Micrometer
  
  There is no Nagios server and the NRPE daemons have been removed from every
  host, so the properties files written under /var/log/services were being
  produced for nobody.
  
  Deleted:
  - CronMetricsService: zero references. Spring instantiated the @Service so its
  constructor registered three meters, but nothing ever incremented them --
  cron_execution_* read 0 in prometheus while cron_job_count_total (from
  CronJobMonitorAspect) had recorded 1,597 executions.
  - NagiosMonitoringScheduledSkeleton.
  
  Removed the nagios properties writes from ScheduledSkeleton (-155 lines) and
  KnowlarityCallMonitorScheduler (-46, including its now-purposeless
  markTaskComplete helper). These recorded a per-job 0/1 status that
  CronJobMonitorAspect already captures properly as success, failure and
  duration metrics.
  
  Kept the two signals that are genuinely useful: SMS gateway balance and the
  ThinkWalnut recharge wallet balance now publish as Micrometer gauges via the
  new BalanceGauges component, scraped from /actuator/prometheus. -1 means 'not
  read yet' so a scrape before the first run is distinguishable from a real zero.
  
  No behaviour change to any scheduled job. Compiles clean.
