fix(copilot): RPC DataError reconstruction, chat stream reconnection

Fix two issues:

1. RPC DataError deserialization crash: When the database-manager
   returns a 400 for a Prisma DataError/UniqueViolationError, the
   client-side reconstruction crashes because DataError.__init__
   expects a dict but exc.args only contains a string message.
   Wrap the string in the expected dict structure so the exception
   is properly caught by callers (e.g. workspace file overwrites).

2. Chat stream reconnection on page refresh: The AI SDK's built-in
   resume:true fires before message hydration completes, causing
   hydrated messages to overwrite the resumed stream. Replace with
   manual resumeStream() called after hydration + active_stream
   detection. Show the stop button immediately when an active stream
   is detected (isReconnecting flag) and prevent sending new messages
   until reconnected.
