Add dynamic route matching and validation improvements

Introduces dynamic route parameter support in route path computation and schema matching. Adds a utility for sending validation errors, updates schema definitions to support header validation, and refactors server middleware to handle header, body, and query validation with improved error handling. Also adds a placeholder user route and updates dependencies to include 'path-to-regexp'.
