Refactor OverviewView and NoLoginView to integrate Character3D component

- Replaced avatar display logic in OverviewView with a 3D character representation based on user gender and age.
- Updated NoLoginView to utilize Character3D for displaying mascots, enhancing visual consistency.
- Removed outdated avatar positioning logic and related computed properties for improved code clarity and maintainability.
- Adjusted CSS styles for better layout and responsiveness of character displays.
