callebtc 0721c39f89 Route oversize send failure to the active conversation
Addresses review feedback: the size-cap error was posted to the main
mesh timeline, so a user sending from a private chat or channel never
saw it. rejectIfOversized now posts to the private conversation
(addPrivateMessageNoUnread) or channel (addChannelMessage) the send
originated from, falling back to the main timeline for public sends.

Adds regression tests for both routings.
