Clarify permission "HasAccess" behavior (#30585)
Follow #30495 "HasAccess" behavior wasn't clear, to make it clear: * Use a new name `HasAnyUnitAccess`, it will be easier to review related code and permission problems. * Separate everyone access mode to a separate field, then all calls to HasAccess are reverted to old behavior before #30495. * Add new tests. --------- Co-authored-by: Giteabot <teabot@gitea.io>
