[Due for payment 2026-06-25] Upgrade `lottie-react-native` to the latest version

[mountiny]

Problem

The app was pinned to lottie-react-native 6.5.1 with four custom patches (bridgeless, RN 77/80/83 support) to keep Lottie working on newer React Native versions. Those patches added maintenance overhead and blocked a clean upgrade path as React Native continued to evolve.

Solution

Upgraded lottie-react-native from 6.5.1 to 7.3.8, which natively supports the latest React Native version. Removed the four upstream patches that are now included in the library; only the recycling patch remains (renamed for 7.3.8). Added @lottiefiles/dotlottie-react for web and configured its WASM binary to load from the Expensify CDN to avoid CSP blocks.
