📧 fix: Restore invite-user CLI (#14436)

* fix: restore invite-user CLI

* fix: guard createInvite failure shape in invite-user CLI

createInvite resolves to { message } on error rather than throwing, so the
CLI interpolated it into the register link as [object Object] and emailed
an unusable invite.

* fix: normalize invite email before token creation

findToken lowercases its email query but the Token schema has no lowercase
setter, so a mixed-case address passed to the CLI was stored verbatim and
the resulting invite could never be redeemed.
