Chore(UI): Add test.slow() to CSVImportWithQuotesAndCommas spec to cover slow responses in 1.13 AUT runs (#27885)

The test consistently lands at the 60s test-timeout boundary on 1.13 AUT
(image n56+) where the backend CSV-import flow takes ~50s end-to-end —
matching the precedent set by #27782 for customProperties. test.slow()
triples the timeout to 180s so transient AUT jitter no longer flakes the
test.
