feat(ui): animated boot splash and loading screen
Show a Lottie-animated splash while the app bundle boots and dismiss it once WebAppComponent initialises, plus a reusable mifosx-loading-screen component with loading and error animations. lottie.min.js is served from the lottie-web package instead of being vendored into src/assets.
