refactor(tests): rename test files to match cj-*-lib.el modules

The earlier cj-cache and cj-org-text rename commits renamed the
modules but missed renaming the test files.  Bring them in line:

- tests/test-cj-cache.el -> tests/test-cj-cache-lib.el
- tests/test-cj-org-text-sanitize.el ->
    tests/test-cj-org-text-lib-sanitize.el

Update file headers, provide forms, and the in-commentary references.
No behavior change.

+;;; test-cj-org-text-lib-sanitize.el --- Tests for the Org-safe text sanitizers -*- lexical-binding: t; -*-
+
+;;; Commentary:
+;; Unit tests for `cj/org-sanitize-body-text', `cj/org-sanitize-property-value',
+;; and `cj/org-sanitize-heading' in cj-org-text-lib.el.  Pure string helpers
+;; for safely composing Org content from external sources (calendar
+;; bodies, web-clipped HTML, mail subjects, AI transcripts).  Originally
+;; lived in calendar-sync.el under `calendar-sync--sanitize-*' names.
