Another 🍪 from #2884.
The RPC bank needs to be updated regularly by the Tvu as it processes and freezes banks, to ensure RPC continues to serve recent results back to clients.
This is only a partial solution to this problem, by plumbing the mechanism to perform the bank updates. What's missing still (from #2884) is an update to the Tvu rotation signal to share a recently frozen bank back with fullnode so it can update the RPC. Until that's in place fullnode just gives the RPC the working bank, which is no less broken than what it currently does.
