feat(settings): unify Streamystats + Marlin URL inputs via the resolver

- jellyfinProbe (/System/Info/Public, ProductName check) + reachabilityProbe (services with no health route).

- ServerUrlStatusText: compact resolver status for ListItem-row layouts.

- Streamystats + Marlin: resolve the URL on blur (https-first, http fallback) and store the canonical URL; inline status feedback.
