build(rn): lint every Swift file in the integration app

[kieran-osgood-shopify]

What changes are you making?

lint_swift named three files by hand, so the other Swift files in the integration app went unlinted. Point SWIFT_PATHS at the two directories instead, then fix the violations that surface.

Delete CheckoutDidFailTests.swift. It holds an empty class and a TODO that promises to restore five tests. Those tests asserted a __typename discriminator on the error payload, and the wire format dropped it — EventSerializationTests now asserts the field is absent. The payload coverage already moved to ShopifyEventSerialization, which those tests reach directly instead of through a mock event emitter.

The remaining diff is SwiftFormat output on four test files.

How to test

cd platforms/react-native && ./scripts/lint_swift

Reports 0 violations in 12 files.

Measured from the PR base SHA and PR head SHA. The file breakdown shows uncompressed sizes within each package artifact, so individual files do not sum to the compressed artifact total. This comment reports package artifact sizes only; it is not a final app binary-size report.
