fix: allow forking a chat that holds a stale unfinished message (#30131)
Forking returned 409 "Wait for the current response to finish before forking." forever once any assistant message anywhere in the chat was left at done = false, with nothing generating and even when that message sat on a branch that was not being forked. Interrupted turns leave the flag behind and nothing clears it, so an affected chat could never be forked again.

The endpoint now refuses only while a task is actually running, which is the check /compact has always relied on by itself. A message still unfinished on the forked branch is marked done in the copy so the fork does not open showing a spinner, while a turn paused waiting on tool approval keeps its unfinished state and its pending call so the fork still shows the prompt. The source chat is left untouched either way.

The client-side check had the same shape of bug: it read history.currentId instead of the message actually being forked, so a paused last turn also blocked forking earlier, finished messages. It now reads the message it is about to fork.

Fixes #30128
