feat: Add automation service with workflow execution, scheduling, run history, and comprehensive test coverage
- Add AutomationService struct with database dependency and NewAutomationService constructor - Add AutomationFilter struct with enabled/type fields for filtering automations - Add List method with enabled/type filtering, created_at DESC ordering, and context support - Add Get method with ID lookup, gorm.ErrRecordNotFound handling, and error wrapping - Add CreateAutomationInput struct with name/description/type/enabled
