refactor(org-refile): name the two refile advices so they can be removed

- Both were anonymous lambdas advising org-refile and org-refile-get-targets.
- An anonymous advice can't be advice-removed by reference.
- So deleting one from source left a live daemon still running it.
- Extracted both to named defuns and installed them remove-then-add.
- Now each reloads to a single copy and is removable by reference.
- Added unit tests for the target-visiting logic, which had no coverage.

+;;; test-org-refile-config--advice-helpers.el --- Tests for the refile advice helpers -*- lexical-binding: t; -*-
+
+;;; Commentary:
+;; Unit tests for the two named advice helpers extracted from anonymous lambdas
+;; in the org-refile use-package :config block:
+;;
+;;   cj/org-refile--save-all-buffers          (:after org-refile)
+;;   cj/org-refile--ensure-targets-in-org-mode (:before org-refile-get-targets)
+;;
+;; They were anonymous `(lambda (&rest _) ...)' advices, which cannot be
+;; `advice-remove'd by reference and cannot be tested.  Naming them makes both
+;; possible.  The install-by-reference and removability are verified live in the
+;; daemon (the :config block doesn't run under batch make test); these tests
+;; pin the extracted logic.
+;;
+;; Test organization:
+;; - Normal Cases: ensure-targets visits each string-named target
+;; - Boundary Cases: empty targets, non-string cars, mixed list
+;; - Error Cases: a nil target list is a no-op
+;;
