Enhances data handling and geographic mapping

Refactors dashboard to use actual metrics for country data,
removing dummy data for improved accuracy. Integrates the
country-code-lookup package for geographic mapping, adding
comprehensive country coordinates. Increases performance and
data validation across API endpoints and adjusts WordCloud
component size for better visualization.

Enhances session handling with improved validation logic,
and updates configuration for allowed origins.
