Origin master.m3u8 contains broken double-tokened URLs after Rok's
encoder change (e.g. bcdn_token=...&token_path=... + ?token=...).
Old regex matched only 'folxplay.b-cdn.net' so it skipped the broken
'folxlive.b-cdn.net' URLs and the player got malformed double tokens.
New regex matches any CDN URL ending in streamN_NNNNp.m3u8 and
rebuilds a clean folxlive URL with our 4h token, ignoring whatever
mess the upstream sends.
