Subject: [PATCH] test(update): spell expected mise owner paths the way the
 detector reports them

On Windows two update-mise tests failed in a lane=all run (windows 7/9):
the detector reports installPath and toolRoot for a drive-letter or UNC
path with forward slashes, so the lexical and resolved candidates compare
in one spelling, while the fixture built its expectations with native
path.join (backslashes). Detection itself was correct: installer, tool,
backend and install boundary all matched, and the 8.3 RUNNER~1 prefix was
identical on both sides.

The fixture now spells its expected owner paths through reportedPath, and a
platform-independent test pins the reported spelling for backslash and
forward-slash Windows inputs, so a change to it fails on every OS instead
of only on the Windows shards.
