chore: dev proxy config, sprite animator refactor, cleanups

- add vite dev proxy for `/ingress` to forward requests to backend https://onefeel.brother7.cn
- update .env.development to use relative proxy paths instead of full backend URLs
- move SpriteAnimator component to correct directory, update all imports and global type declarations in components.d.ts
- remove unused CSS styles and fix styling for ChatTopNavBar component, including switching to van-icon and hardcoding temporary site name
- uncomment and enable the ChatMainList component in home page
- clean up unused code, fix formatting, and set default client ID in src/utils/request.ts
- comment out redundant uni API calls in ChatMainList to simplify code
- update WebSocket URL handling to support relative paths in ChatMainList
