Add terms and conditions checkbox to sign-up methods (#45)

A checkbox has been added for user acceptance of terms and conditions during sign-up. This change includes adding a new adjustable flag in the configuration to control the display of the checkbox. A new file "terms-and-conditions-form-field.tsx" is added to handle the checkbox UI part. Also, localization support has been added for the feature.
