[PR] feat(portal): de-Thrift user/experiment storage listing to gRPC (Track D, D4.3) [airavata-portals]

   ## Summary
   
   Track D (D4.3): repoint the storage path views and the create-user-storage-dir signal from the legacy `airavata_django_portal_sdk` `user_storage` helpers to the gRPC `storage` facade.
   
   - **`UserStoragePathView`** get/post/put/delete + **`ExperimentStoragePathView`** → `storage.dir_exists` / `list_dir` / `get_file_metadata` / `create_dir` / `delete_dir` / `delete_file` (+ the `_storage_upload_and_register` helper for uploads). A new `_user_storage_path` resolves a request path to the absolute `~/`-prefixed path the facade expects, including experiment-relative paths (via the experiment data dir).
   - New **`grpc_adapters.user_storage_file` / `user_storage_directory`** map the gRPC `FileMetadataResponse` (name/path/size/modified_time/content_type/data_product_uri — populated server-side by apache/airavata#652) to the dicts the storage serializers read.
   - **`UserStorageFileSerializer.downloadURL`** now builds the portal `download-file` URL directly from the file's data product URI; **`UserHasWriteAccessToPathSerializer`** drops the remote-API `user_storage.listdir` branch (the gRPC path talks to the backend directly, not a remote portal proxy).
   - **`signals.create_user_storage_dir`** → `storage.create_dir` / `create_symlink`.
   - The deprecated `download_file` view redirects to the gRPC `download-file` endpoint.
   - Drop the now-unused `user_storage` (and `queue_settings_calculators`) imports from `views.py` / `serializers.py`.
   
   ## Depends on
   
   apache/airavata#652 — adds per-file `modified_time` / `content_type` / `data_product_uri` to the gRPC listing and fixes SFTP file delete. Without it, listings would lose those fields and `delete_file` would fail. Merge #652 first.
   
   ## Validation
   
   REST/JSON contract unchanged. `manage.py check` clean. **Live against the running backend:** `UserStoragePathView` GET lists `~/tmp` (200) with each file rendering `name`/`size`/`createdTime`/`modifiedTime`/`mimeType`/`dataProductURI`/`downloadURL`/`userHasWriteAccess`; upload (creates the dir + registers a data product), content overwrite, and DELETE (204, file actually removed) all round-trip.
