Raja SubramanianandClaude Opus 5.5 a67eb7b560 sfu: send padding in the slot of a dropped out-of-order packet (#4979) ...

On a gap the RTP munger gives the missing sequence numbers outgoing slots.
If a late packet then arrives and is dropped, nothing is ever sent in its
slot, and a subscriber that finds frame references by sequence number
stalls until a key frame. The forwarder now flags such drops, and the
downtrack sends a one byte padding only packet in the slot.
