* refactor: export Settings type, Setup returns value * refactor: resolver.Setup takes explicit Settings struct * refactor: GetHeadersWithoutTrustedHeaders takes explicit header params * refactor: server constructors take narrow config * refactor: Router struct with handler methods, remove geoSvc global * refactor: wire DI through main, remove setting.App references * refactor: remove App global, use returned Settings * refactor: update router tests for DI * chore: fix lint issues — rename ServerTimeouts to Timeouts, fix shadowed variables
