feat(inbounds): apply remark template to Export all inbound links

Export-all now renders links through the subscription engine via a new GET /panel/api/inbounds/allLinks endpoint, so the configured remark template (name-only display part) is applied per client -- matching the client info/QR pages. Previously it generated links client-side with a hardcoded inbound-email remark.

Host-aware: managed Host endpoints win over the plain link, so HOST and per-host variants render; duplicate client JSON entries are deduped by email and the list is scoped to the logged-in user.
