Refactor Indeehub integration and enhance deployment documentation

- Updated Indeehub references throughout the codebase, changing the name from "IndeedHub" to "Indeehub" for consistency.
- Implemented a virtual app structure for Indeehub, allowing it to open an external URL without requiring a container.
- Enhanced deployment scripts and documentation to clarify SSH access and password management for Indeehub.
- Improved error handling and retry logic in various components to ensure better user experience during onboarding and app interactions.
- Updated CSS for visual enhancements and added new buttons for improved navigation in the AppLauncherOverlay.
