Frontend (NordModal.vue):
- Server selector gets show-search with the option label set to
`${cityName} ${name} ${hostname}` so admins can find a specific
server inside a 100+ entry country list by typing.
- Each option renders the load as a colored a-tag (green <30%,
orange 30-70%, red >70%) instead of plain text — quicker visual
scan when sorting through servers in the dropdown.
Backend (nord.go):
- GetCountries / GetServers now check resp.StatusCode and return
"NordVPN API error: <status>" on non-200, matching the pattern
GetCredentials already used. Previously a 4xx/5xx body was
returned as a "success" string and the frontend silently failed
to parse it, surfacing only as an empty "No servers found".
- GetCredentials drops its own ad-hoc 10s http.Client and reuses
the shared nordHTTPClient (15s) — one client, one timeout.
