AbstractUnitTestCase::mockWithoutConstructor() / mockWithConstructor() - build a test
double with the constructor disabled or invoked (with constructor arguments), keeping the
non-overridden methods real. Method overrides become stubs (a Closure body, a return value,
or null for a type-safe default) and property overrides are set via reflection. Built as a
stub on PHPUnit 12+ (so no "mock object without expectations" notice is raised); works across
PHPUnit 10.5-13.

ServicesTrait now skips (instead of erroring) when the backing client is unavailable: the
memcached helpers skip when ext-memcached is not loaded, and the redis helpers skip when the
predis/predis package is not installed.
