test(command): port install/reinstall/require/update tester tests

The ApplicationTester harness is in place, so port the four command
test bodies that were todo!() stubs and replace the stale "requires
ApplicationTester ... not implemented" ignore reasons with the actual
remaining Phase-C blockers. test_install_command_errors now passes;
the rest stay #[ignore] pending installer registration, the update
command InputDefinition, and the InstallationManager::execute port.
