Fix dead channels across Italy, Spain, Russia, UAE, USA (iptv-checker driven)

Cross-referenced the CI iptv-checker's failed-channel report against
each country list, verified every replacement URL with curl before
applying, and removed one genuine duplicate (Telecolor International).
Real geo-blocked national-broadcaster 403s and CI-runner false
positives (esp. HTTP 408 timeouts, which turned out unreliable) were
left untouched rather than guessed at.

Italy: 6 fixed, 1 duplicate removed
Spain: 16 fixed
Russia: 3 fixed
UAE: 13 fixed
USA: 10 fixed
