20 engine tests failed on Windows on clean main. Three real bugs on
case-insensitive volumes (Windows, default macOS APFS) caused most of them:

- Renaming a photo probed `a.XMP` before `a.xmp`. On a case-insensitive
  volume the upper-case spelling "exists" when only `a.xmp` is there, so the
  sidecar was moved as `Trip.XMP` (and its retained-packet record was taken
  under the wrong spelling). Upper-case candidates are now used only when the
  folder lists them exactly (new `MoveFs::listed`).
- `RealFs::same_file` on Windows (no file id in std) depended on argument
  order: `same_file("Trip.XMP", "Trip.xmp")` was false when `Trip.xmp` is the
  real entry, so saving after a partial rename reported a phantom collision.
  It is now symmetric, and also requires the names to differ only by case
  (two different files with equal size and mtime were "the same").
- Saving metadata picked the sidecar spelling by `is_file()`, lower case
  first, so the atomic write renamed an existing `Trip.XMP` to `Trip.xmp`.
  The spelling the folder lists now wins.

The rest were fixtures: FakeFs fault paths, catalog paths and expected
paths spelled with `/` while the code joins with the host separator.

Regression tests: case_insensitive_renames_keep_each_sidecars_spelling
(FakeFs, every platform; fails without the fix) and
same_file_spellings_are_symmetric_on_windows. Linux behaviour unchanged.
