v4.8.0: Add scheduled report generation

- ScheduledReportService (@MainActor, headless/storage-backed like
  DomainMonitoringService): builds the latest report for every tracked domain
  from persisted history, exports it via DomainReportExporter in the
  configured format (markdown/PDF/JSON), writes it to a local Documents
  subdirectory, logs the run, and fires a "Scheduled Report Ready" local
  notification.
- ScheduledReportScheduler mirrors DomainMonitoringScheduler's BGTaskScheduler
  approach with its own task identifier (net.cleberg.DomainDig.report.schedule,
  added to Info.plist) and a daily/weekly cadence.
- ScheduledReportsView (Settings → Scheduled Reports): enable toggle, cadence
  and format pickers, "Generate Now", and a log of past reports each shareable
  via the existing ExportPresenter share sheet.
- Gated behind the existing .automatedMonitoring capability (Pro), consistent
  with monitoring being the other background-automation feature.
- Settings/logs persist via UserDefaults (DomainExportFormat is now Codable),
  not DomainDataPortabilityService backup/restore — this is local automation
  configuration, not user-authored content, same reasoning as v4.7.0's
  watchlist saved views.
