fix(sdk): add 'deepObject' to ArrayStyle instead of silently falling back to 'form'

When an array query parameter has `style: deepObject` the generator was
emitting `style: 'deepObject'` in sdk.gen.ts, but `ArrayStyle` in every
client bundle did not include that value, causing a TypeScript compile
error in the generated output.

The correct fix is to add `'deepObject'` to the `ArrayStyle` union in all
client bundles (client-core, client-nuxt, client-next, client-angular,
custom-client). The generator now faithfully preserves the style from the
spec. Users who need bracket notation serialisation (products[0]=...) can
supply a custom `querySerializer`.
