+  Creates a join request in status :submitted (for approval UI tests).
+
+  Uses the public flow: submit_join_request then confirm_join_request with a known token.
+  Returns the JoinRequest struct so tests can use its id for approve/reject.
+
+  ## Parameters
+    - `attrs` - Optional map: :email, :first_name, :last_name, :form_data, :schema_version.
+      Defaults: unique email; confirmation_token is generated and used internally.
+
+  ## Returns
+    - JoinRequest struct with status :submitted
+
+  ## Examples
+
+      iex> request = submitted_join_request_fixture()
+      iex> request.status
+      :submitted
+
+      iex> request = submitted_join_request_fixture(%{first_name: "Jane", last_name: "Doe"})
