Refactor server package: split handlers and routes into separate files
- Move all handler functions to handlers.go - Move setupRoutes to routes.go - Clean up server.go to only contain core server logic - Add missing GetASDetails and GetPrefixDetails to mockStore for tests - Fix linter errors (magic numbers, unused parameters, blank lines)
