feat: Implement Entity Suggestion Manager and Modal components
- Added EntitySuggestionManager.vue to manage entity suggestions and authentication. - Created EntitySuggestionModal.vue for displaying suggestions and adding new entities. - Integrated AuthManager for user authentication within the suggestion modal. - Enhanced signal handling in start-servers.sh for graceful shutdown of servers. - Improved server startup script to ensure proper cleanup and responsiveness to termination signals. - Added documentation for signal handling fixes and usage instructions.
