feat(auth): implement session token creation and verification for enhanced security

feat(api): require session authentication for admin routes and improve error handling fix(api): streamline project image generation by fetching data directly from the database fix(api): optimize project import/export functionality with session validation and improved error handling fix(api): enhance analytics dashboard and email manager with session token for admin requests fix(components): improve loading states and dynamic imports for better user experience chore(security): update Content Security Policy to avoid unsafe-eval in production chore(deps): update package.json scripts for consistent environment handling in linting and testing
Prevent white screen: wrap ActivityFeed in error boundary and improve ClientProviders error handling
