Address Codex review feedback on PR #6627

- Classify IPv4/IPv6 link-local addresses (169.254.0.0/16, fe80::/10) as
  LAN in Jellyfin location parsing - they can't traverse a router, so a
  false WAN reading was possible for common autoconfig/link-local sessions.
- Fix portrait video resolution mislabeling - a 1080x1920 clip was
  classified off its long-axis height (1920) and showed as 1440p. Classify
  by the short axis instead so orientation doesn't flip the result.
- Raise the compact-mode status column breakpoint from 420 to 540px - at
  420 the fixed-width user (200px) and status (190px) columns left almost
  no room for the currentlyPlaying column, the widget's primary content.
- Document the new resolution indicator in the media-server widget docs.
