ci: find text fields by placeholder value, compare typed text ignoring case

Run 38448094338 reached the chat list and typed into the search field, which showed "Ci smoke" and the Search in Directory row, but the check looked for "ci smoke": the keyboard capitalizes the first letter. SwiftUI text fields expose no accessibility label, only the placeholder as the value of an empty field, so the fields are now tapped by value.

This run tests the smoke test end to end, with the core library restored from cache.
