Mount this app's per-user settings — a private ~/.config-style filesystem,
auto-provisioned for the signed-in user and isolated to THIS app (the host
chroots it; a different app can never name it). Read/write config files through
the returned mount. Rejects with a SpaceError (auth-required) when
signed out. Capability: baseline settings:app.
