Walkthrough

Replaces the mocking library from github.com/golang/mock to go.uber.org/mock across the repo: updates go.mod, the tools blank import for mockgen, the generated mock file import, and gomock imports in several test files.

Module / Tooling go.mod, tools.go	Replaced github.com/golang/mock requirement with go.uber.org/mock v0.6.0; changed blank tool import for mockgen to go.uber.org/mock/mockgen.
Generated mocks pkg/actuators/client/mock/client_mock_generated.go	Updated import path for gomock from github.com/golang/mock/gomock to go.uber.org/mock/gomock.
Test wiring pkg/actuators/machine/actuator_test.go, pkg/actuators/machine/machine_scope_test.go, pkg/actuators/machine/reconciler_test.go, pkg/actuators/machineset/controller_test.go	Replaced gomock import paths in test files to go.uber.org/mock/gomock; test usage (controllers, matchers, expectations) unchanged.
