feat(alerting): AlertingProperties + AlertStateTransitions state machine

Browse Source 
- AlertingProperties @ConfigurationProperties with effective*() accessors and
  5000 ms floor clamp on evaluatorTickIntervalMs; warn logged at startup
- AlertStateTransitions pure static state machine: Clear/Firing/Batch/Error
  branches, PENDING→FIRING promotion on forDuration elapsed; Batch delegated
  to job
- AlertInstance wither helpers: withState, withFiredAt, withResolvedAt, withAck,
  withSilenced, withTitleMessage, withLastNotifiedAt, withContext
- AlertingBeanConfig gains @EnableConfigurationProperties(AlertingProperties),
  alertingInstanceId bean (hostname:pid), alertingClock bean,
  PerKindCircuitBreaker bean wired from props
- 12 unit tests in AlertStateTransitionsTest covering all transitions
