hls.js: 10s -> 30s segment load cap (iPhone FragLoadTimeout)

The iPhone error 'Playback failed: FragLoadTimeout' + 74 all-200
segment requests = the phone's downlink can't deliver a ~700KB
segment within the 10s cap; hls.js measured the load client-side
while the server finished instantly. Raise maxLoadTimeMs to 30s
(first-byte 20s) so slow-but-alive phone links complete; retries
still bound the truly-dead case. assets v=11.
