Rebuild the /admin/users detail drawer from a read-only profile into an
editable, Office 365-style panel with four sections:
- Username & mail: read-only primary for mailbox users; editable sign-in
(Authentik-only) for mailbox-less identities; "Create mailbox" provisions
a Stalwart inbox for an external-login admin
- Aliases: list/add/remove mailbox aliases (Stalwart), domain-scoped
- Role: member/admin toggle with a primary-account lock (owner, mailbox-less
bootstrap admin, self) and a last-admin guard
- Contact information: display name, first/last name, phone, alternative
email — mirrored best-effort to Authentik attributes + mailbox name
Ownership transfer: "Make owner" (row menu + drawer) plus an owner-side
"Transfer ownership" picker, gated to tenant admins / platform admins so a
departed owner can be replaced; promotes the target and demotes the prior
owner to admin.
Backend (platform-api): contact fields on User; AuthentikClient.updateUser;
StalwartClient.setMailboxName; UsersService updateTenantMember,
changeMemberPrimaryEmail, list/add/removeMemberAlias, createMailboxForMember,
transferOwnership; new DTOs and tenant-member routes. All mutations audited.
Portal: Nuxt proxies for the new endpoints + extended TenantUserDoc.
