Stop the instrumented tests depending on screen width

filteringByCategoryHidesTheOtherCategories matched the Medicine chip by text and
clicked it. The filters are a LazyRow, so a chip that does not fit on screen is
never composed and cannot be found. It passed on a 1080x2400 emulator and failed
on CI's narrower one. The row now carries a test tag and the test scrolls to the
chip, and takes the label from resources rather than hardcoding English.

Also raises the waitUntil timeout from 5s to 15s. Three tests timed out on CI
purely because a cold emulator is slower than a warm local one, which reports as
a behaviour failure rather than as the machine being busy.
