The same maxBitrate was written into every encoding, so a 1.5 Mbps cap
could mean 4.5 Mbps aggregate. Distribute proportionally to the layers'
existing ratios (floor, so never over). Tested with a 3-layer case.

A null cap only removed the key from the sticky settings and applyToRoom
then skipped that sender, leaving the previously written maxBitrate /
maxFramerate live on the RTCRtpSender — contrary to the host contract
documented in cinny's CallControl. Track which keys this module wrote per
sender and write them back as undefined on clear. Unit-tested.
