feat(clients,routing): label inbounds by remark with tag fallback

Inbound pickers and chips across the Users area, the inbounds attach-clients modals, and the routing rule inbound-tags selector showed the auto-generated tag (in-443-tcp). Show the inbound remark when set, falling back to the tag.

Only display labels change; option values keep using the inbound id (or tag for routing rules, which match inbounds by tag), so filtering, attaching, and saved rules are unaffected. Routing reads remarks via a shared useInboundOptions hook that reuses the existing options query cache.
