DefaultDataRoot, the pointer-file location and the portable-mode root
all read machine-global locations (APPDATA, AppContext.BaseDirectory),
so the override→portable→pointer→default precedence in DataRoot/
IsDataLocationConfigured was previously untestable beyond the override
case. Added three internal overrides (BootstrapDirOverride,
PortableBaseOverride, DefaultRootOverride) as sandboxing seams, and a
new AppPathsResolutionTests class covering every precedence branch:
default-only, portable-beats-pointer, pointer-beats-default, a blank
pointer falling back to default, "already has data" counting as
configured, and override beating everything. Both AppPaths test
classes share the "AppPaths" xUnit collection since this state is
static.
