[MEDIUM] M1: manualImport always returns HTTP 400 — successful imports appear as failures

[rubenvdlinde]

Severity: MEDIUM

Location: lib/Controller/SettingsController.php lines 1020–1023 (manualImport)

Description:
The success branch of manualImport is an empty if block:

if ($result['success'] === true) {
    // empty
}
return new JSONResponse($result, 400);

Every response — including successful imports — returns HTTP 400. The UI therefore always displays the import as failed, regardless of the actual outcome.

Suggested fix:

return new JSONResponse($result, $result['success'] === true ? 200 : 400);
