feat(sidebar, settings): enhance project management and UI navigation

- Removed trash functionality from the sidebar component, including the associated button and event handlers.
- Added a new "Danger Zone" section in the settings view for project deletion, featuring a confirmation dialog.
- Implemented smooth scrolling and active section highlighting in the settings sidebar for improved navigation.
- Updated various UI elements for better consistency and responsiveness.

These changes streamline project management and enhance user experience within the application.
