test(acf): cover integration boot and match-rule edge cases

isSupported(), registerHooks() and the constructor otherwise run during the test bootstrap, before coverage collection starts, so they never register as covered. Instantiate the integration directly to exercise them, mirroring PolylangTest and WpmlTest.

Also cover the two remaining match_rule branches: a screen pointing at a non-existent post, and a rule value that matches no bound post type. This brings AdvancedCustomFields to full line coverage.
