Remove unused background.jpg asset from RevenueCatUI

[MonikaMateska]

Motivation

We have a 106 KB background.jpg that can no longer reach the screen: it's only referenced as the legacy default paywall's images.background, and every path that builds that paywall now renders DefaultPaywallView instead.

Resolves PWENG-220.

Description

background.jpg could previously be reached through a few different paths, but none of them actually display it anymore:

• The default paywall paths always fall back to the standard default paywall, which uses its own imageset instead
• The Paywalls V2 footer fallback can still render Template 2, but footer layouts don’t display a background image
• The loading paywall was the only place that could still read the background image directly, but that view is no longer used in production. The current loading state uses the default paywall instead. The old loading view now only shows up in snapshot tests and renders with a plain background

Note

Low Risk
Asset and fallback-paywall cleanup with no purchase or auth changes; visible impact is limited to legacy loading/snapshot paths and slightly smaller RevenueCatUI bundles.

Overview
Removes the legacy background.jpg bundle asset (~106 KB) and stops wiring it into default fallback paywall configuration, since production paths no longer display it.

Packaging drops background.jpg from SPM (Package.swift, Package@swift-5.8.swift), CocoaPods (RevenueCatUI.podspec), and the Xcode project. PaywallData.createDefault no longer sets images.background or the backgroundImage constant. LoadingPaywallView uses the standard default paywall only and drops the blurred TemplateBackgroundImageView background plus the paywall variant that cleared the background for shimmer.

Tests update PaywallData validation JSON snapshots so default paywalls expect "background": null, and ImageLoaderTests loads sample image bytes via .withLocalImages instead of the removed default background URL.
