xhamster: move from WebView fallback to server-side native HLS. The scene page
is fetchable server-side and the xhcdn master m3u8 (variants + segments) is
time-bound, not IP-bound (verified cross-IP), so mobile plays the HLS direct
with zero proxy bandwidth. New tubes/xhamster.py pulls the master m3u8 from
SSR HTML and returns type='m3u8' mobile_direct; registry remaps xhamstercom
off _vps_blocked_fallback.
hqporner: add flyflv to the player-iframe host whitelist. hqporner rotated
some players to flyflv.com; the CDN host was already whitelisted but the iframe
host was not, so those scenes returned no stream.
