Both places you add an admin link - a server's own Admin Links section
and the Operations > Admin Links summary page - now offer a "fill from
a known port" dropdown once a server is picked, listing its
agent-reported and manually-noted ports (the same data the Ports
page/card shows). Picking one fills in the URL as
http(s)://<hostname-or-IP>:<port>, guessing https for a handful of
common admin-panel ports, and fills the label too if it's still empty.
The URL field stays fully editable either way.
Shared the address/label logic in a small adminLinkUrl.ts helper used
by both pages. No server-side changes needed - built entirely on the
existing per-server ports and detail endpoints.
