Fix TypeScript errors for production build

- Fixed nullable searchParams with optional chaining and fallbacks
- Fixed recency type handling (string from URL, number internally)
- Removed duplicate Party/User interface definitions, use global types
- Fixed error handling in API routes with proper type checking
- Fixed props access in UI components (placeholder, content types)
- Added missing required props to components
- Fixed type mismatches with next-intl rich text interpolation
