refactor(tests): add mock factories to eliminate test duplication

- Add createMockAuthServiceTestStation() to MockFactories.ts
- Add createMockOCPP20TransactionTestStation() to OCPP20TestUtils.ts
- Replace 19 inline mocks in OCPPAuthServiceImpl.test.ts
- Replace inline setup in 3 OCPP 2.0 transaction test files
