Refactor navigation structure and update asset references

- Swapped routes for Profile and Notification branches in the app's navigation structure.
- Updated the current index for navigation items in TabletNavigationWidget and related pages to reflect the new routing.
- Added a new logo SVG asset to the asset manager for branding consistency.
- Adjusted the pubspec.lock file to downgrade several package versions for compatibility.
