fix: resolve webui build and lint warnings

- Fix critical syntax errors in prompt-textarea.tsx (missing useCallback wrapper)
- Resolve React purity issues (Date.now() during render)
- Fix TypeScript errors (empty interfaces, cache type casting)
- Remove unused variables and imports across components
- Add missing alt props to decorative icons
- Fix useEffect dependency warnings
- Replace 'any' types with proper TypeScript types
- Resolve function hoisting issues in components
- Fix setState in useEffect warnings
- Update API client cache type handling

Build status: ✅ All errors resolved, 29 remaining non-critical warnings
