Refactor imports and types for consistency and remove redundant paths

- Updated relative imports by replacing `@/` aliases with proper `../` paths for consistency.
- Refined type definitions in IPC handlers and repositories (`User`, `Chapter`, `Act`, etc.).
- Simplified return types in `Location` model methods for streamlined usage.
