Fixes for "validate email" & "send validation email" in ACP (#11677)

* confirmObj changes

dont expire confirm:<code>, add a expires field instead
dont expire confirm:byUid:<uid>

on admin manage users display the users email status
	1. verified
	2. verify email sent (pending)
	3. verify email sent (expired)
	4. no email entered

	email in user:<uid> if they have one
	if not check if its in confirm:<code>
	if its not in above cant validate throw error

fix send validate email to use
	email in user:<uid> if they have one
	if not check if its in confirm:<code>
	if its not in above too cant validate throw error
