Merge 793906bb68 into 28b0ad782a

* remove extra gap controller overrides

* new vod endpoint for clips to set discontinuity

ensure tracking-detail playlists emit #EXT-X-DISCONTINUITY (avoids fMP4 timestamp rewrites and playback stalls) while leaving standard recordings behavior unchanged

* use new endpoint
