Summary by cubic

Refactored run results storage to run at completion via RunLifecycleManager and switched storage availability checks to the FileService. This decouples the flow from Postgres and makes storage backend-agnostic.

• Refactors
  • Moved results storage from PostgresService to RunLifecycleManager, storing results asynchronously, updating resultStorageUri via datastore.updateRun, and no longer persisting full result payloads in the DB.
  • Replaced S3-specific isS3StorageAvailable with isFileStorageAvailable in FileService; removed the old check.
  • Updated GET /runs/:runId/results to use the new availability check and a clearer error message.
  • Removed run results storage triggers and org preference checks from PostgresService.
  • Clarified shared type comments to reference FileService instead of S3.
  • Adjusted Next.js types import path in web/next-env.d.ts.
