Remove legacy config API routes and tests

Delete legacy configuration API handlers and their tests. Removes src/app/api/config/route.ts (GET/PUT for config), src/app/api/config/[category]/route.ts (category GET), and tests/api/config.routes.test.ts. This cleans up deprecated/duplicated config endpoints and associated tests from the codebase.
