Support for Nested Dynamic Routes

[dpouris]

• Renamed isDynamicRouteMatch to isDynRouteMatch for consistency.
• Enhanced matching logic to support nested dynamic segments in routes (e.g., /path/:var/:var2).
• Added prepare method in Ctx to handle URL and dynamic path parsing.
• Refactored constructPathRoutes to resolveDynRoute for clarity.
• Updated dynamic route examples to include nested route scenarios.
• Modified and added tests to cover new functionality and ensure robustness.
• Improved internal documentation and cleaned up code for better readability.

This pull request addresses and closes the issue of supporting nested dynamic routes in the isDynRouteMatch function.
