Isolate XDG dirs in shell tests that launch quickshell with a fake HOME

Faking HOME alone was never enough: the shell QML and the agent usage
updater read XDG_STATE_HOME and XDG_CACHE_HOME directly, so a test
quickshell inherited the session's real paths. The bar widget contract
test instantiated the agents widget, whose refresh ran the real
collectors against the empty fake HOME and wrote hollow "Waiting for
auth" records into the developer's real usage data files — hiding the
agents widget from their bar — while littering the real cache with
per-tmpdir scan files.

Point XDG_CONFIG_HOME, XDG_CACHE_HOME, and XDG_STATE_HOME under the fake
home in every test that boots quickshell with one.
