Introduced a two-tier media pipeline with dynamic disks, asset tracking, admin controls, and alerting around
  upload/archival workflows.
  - Added storage metadata + asset tables and models so every photo/variant knows where it lives
 (database/migrations/2025_10_20_090000_create_media_storage_targets_table.php, database/  migrations/2025_10_20_090200_create_event_media_assets_table.php, app/Models/MediaStorageTarget.php:1, app/
    Models/EventMediaAsset.php:1, app/Models/EventStorageAssignment.php:1, app/Models/Event.php:27).
  - Rewired guest and tenant uploads to pick the event’s hot disk, persist EventMediaAsset records, compute
    checksums, and clean up on delete (app/Http/Controllers/Api/EventPublicController.php:243, app/Http/
Controllers/Api/Tenant/PhotoController.php:25, app/Models/Photo.php:25).
  - Implemented storage services, archival job scaffolding, monitoring config, and queue-failure notifications for upload issues (app/Services/Storage/EventStorageManager.php:16, app/Services/Storage/
    StorageHealthService.php:9, app/Jobs/ArchiveEventMediaAssets.php:16, app/Providers/AppServiceProvider.php:39, app/Notifications/UploadPipelineFailed.php:8, config/storage-monitor.php:1).
  - Seeded default hot/cold targets and exposed super-admin tooling via a Filament resource and capacity widget (database/seeders/MediaStorageTargetSeeder.php:13, database/seeders/DatabaseSeeder.php:17, app/Filament/Resources/MediaStorageTargetResource.php:1, app/Filament/Widgets/StorageCapacityWidget.php:12, app/Providers/Filament/SuperAdminPanelProvider.php:47).
- Dropped cron skeletons and artisan placeholders to schedule storage monitoring, archival dispatch, and upload queue health checks (cron/storage_monitor.sh, cron/archive_dispatcher.sh, cron/upload_queue_health.sh, routes/console.php:9).
