eporner: play through a redirect proxy; the signed CDN links expire after 2h

Expired eporner mp4 links are answered with a 302 to static.eporner.com/
na.mp4, a one-minute "watch it on eporner.com" clip. The links expire
exactly two hours after the /xhr/video call, so anything played from a
favourite, history entry or a list left open past that hit the decoy.

New /proxy/eporner/{alnum_id}/{height} re-resolves the hash/xhr chain at
play time and 302s to the matching (else best) quality. The eporner
provider and melonstube's eporner destinations now emit these proxy URLs;
verified app clients get the best quality as video.url via the existing
redirect-proxy rule. Verified live: proxy -> fresh CDN link -> 206 video/mp4
for app and non-app clients.
