swap and auction estimations fail

[TalDerei]

I've been getting this estimation error when trying to perform swaps / auctions.

Hm, I'm actually getting HTTP 412s (Precondition Failed). @TalDerei , which RPC are you using?

[TalDerei]

@jessepinho I don't recall, but it could be related to the fact that the RPC might not support simulation? In this context, it's not immediately clear to the user how much they're swapping if they need to manually inspect the transaction approval dialogue for that information.

tagging https://github.com/penumbra-zone/web/issues/936 as relevant

412 precondition failed likely means no price data is available to create an estimation. this will succeed if you make at least one trade.

408 unimplemented likely means the node operator has not run pd with --enable-expensive-rpc

[turbocrime]

i encountered both of these today and i believe they were visible in console, will take another look at error propagation soon

Ah — can production RPC nodes run pd without that flag? If so, sounds like we need to handle that case.

The released version of pd makes that flag a no-op, but yeah, error handling would be good.
