The new informational Windows job surfaced 91 failures: four real bugs (fixed in
the previous two commits) and a long tail of POSIX assumptions in the tests
themselves. None of them assert behaviour that differs on Windows, so they are
fixed rather than skipped wherever the behaviour is the same:
* Path spelling: expectations built with `str(tmp_path)` are compared through an
identity helper (`normalize_root_identity`) or the platform's separator, since
the code hands out forward-slashed business paths while `str()` is native.
* Root labels: `_root_display_labels` prefixes the drive on Windows ("C: loras"),
so label assertions compare the final path component or derive the expected
label from the same helper.
* `~` expansion reads USERPROFILE (ntpath), not HOME; timer granularity rounds
0.1s down; a case-only rename counts as "already named" via `os.path.normcase`.
* Genuinely POSIX-only strategies are skipped with a reason instead of failing:
the headless clipboard fallback, dbus file-manager selection, xdg-open, and
the case-fold index test that simulates a case-sensitive filesystem.
Add a reusable directory-picker modal backed by a new generic
POST /api/lm/browse-directory endpoint (browse logic extracted from the
recipe batch-import handler into py/utils/directory_browser.py) and wire
a browse button plus advisory validate-path feedback (POST
/api/lm/validate-path) into the settings path inputs: recipes path,
example images path/local root, and the extra-folder/model-path rows.
The browse button insets into the right edge of static inputs so narrow
settings rows keep their single-control layout.
Translations for the new settings.directoryPicker and
settings.pathValidation keys are filled in for all 9 locales.
