Glucose Alarms: user-configurable list of alarms

* GlucoseAlertsStore (UserDefaults) holds [GlucoseAlert] +
  GlucoseAlertConfiguration. Seeds 4 default alarms (urgent-low +
  forecasted-low disabled, low + high enabled) on first launch. At
  least one alarm of each type is retained (delete-protected).
* GlucoseAlertCoordinator evaluates reading-based + forecast-based
  alarms, issues via TrioAlertManager, retracts on recovery.
  Hierarchical suppression: urgent-low silences low; urgent-low / low
  silence forecasted-low.
* ForecastedGlucoseEvaluator: min of available predBG curves at +20m.
* SwiftUI module GlucoseAlerts — alarm list, inline Day/Night
  DatePickers, per-type editor, AlarmAudioSection with tone preview and
  Play Sound toggle, window icon per row, Override Silence & DND toggle.
* Retire GlucoseNotificationSettings module, GlucoseNotificationsOption
  enum, lowGlucose / highGlucose / addSourceInfoToGlucoseNotifications
  fields. ContactImage and LiveActivity now read settings.low / .high.
* sendGlucoseNotification reduced to badge updates; alarm emission owned
  by the coordinator.
