fix(seerr): check /api/v1/status instead of / for readiness

The root URL returns HTML before Seerr finishes initializing,
causing Radarr/Sonarr addition to fail. Now hits /api/v1/status
which only succeeds after full init, plus adds a 3s settle delay
and a ready log message for consistency with other services.
