fix(ios/spm): link FronteggSwift into every target that links FronteggRN

Under use_frameworks! :static, FronteggRN builds as a static framework and does
not embed FronteggSwift's objects, so any binary that links FronteggRN — the app
target AND the unit-test bundle (inherit! :complete) — linked with unresolved
FronteggSwift.* symbols. frontegg_spm.rb previously *removed* the app-target SPM
link assuming FronteggRN provides it. Instead link the FronteggSwift SPM product
directly into each such target (one XCSwiftPackageProductDependency + a Frameworks
build file per target), located generically by product type
(application + bundle.unit-test); UI-test bundles link neither and are excluded.
Idempotent; result is plutil-lint valid.
