Improve scoping checks for objects (#7739)

#### Rationale
We can improve our parameter validation

#### Changes
- New helpful base class for integration tests,
`AbstractContainerScopingTest`
- New test coverage
- Assorted scoping checks

+/**
+ * Base class for "container scoping" (a.k.a. broken-object-level-authorization / BOLA / IDOR) integration tests. These
+ * tests verify that an action whose {@code @RequiresPermission} annotation is correct for the current container still
+ * rejects an object resolved by a global id that belongs to a <em>different</em> container.
+ *
+ * <p>The repeated scaffolding lives here so each subclass keeps only its data fixture and the action under test:
+ * <ul>
+ *   <li>{@link #createContainer(String)} — make a throwaway child of the junit container (auto-cleaned).</li>
+ *   <li>{@link #createUserInRole(Container, Class)} — make a user with a role assigned in <em>one</em> folder only
+ *       (auto-cleaned). Use this to obtain a caller who is, say, admin in folder A but has no rights in folder B.</li>
+ *   <li>{@link #get(ActionURL, User)} / {@link #post(ActionURL, User)} — dispatch an in-JVM request as a given user
+ *       and inspect the {@link MockHttpServletResponse} status. Parameters travel on the {@link ActionURL}.</li>
+ * </ul>
+ *
+ * <p>Note: WebDAV verbs (MOVE, PROPPATCH, ...) are not served through {@link ViewServlet} dispatch, so a WebDAV test
+ * should still use this class for its container/user fixtures but drive the verb through {@code WebdavServlet} itself.
