Deivid Soto 8207d1d2a9 fix(stream): derive H.264 level from frame macroblocks, not height
Anamorphic 2.39:1 scaled to 1080 height = ~2586x1080 = 11016 MBs, busting
level 4.1's 8192-MB MaxFS -> nvenc "InitializeEncoder failed: Invalid Level"
(libx264: "frame MB size > level limit") -> 0 segments, session stalls. Most
4K rips are 2.39:1, so HLS playback was silently broken for them.

H264LevelForFrame(w,h) derives the level from the real macroblock count
(max of MB-tier and height-tier). hls.go computes output width and uses it.
16:9 unchanged; anamorphic bumps to 5.0 when needed. Discovered + verified
during the trickplay smoke.
