Server-side SwapExactOutput preview. The swap_exact_out_quote FFI op orients
the pool reserves to the requested in/out direction, prices via the shared
amm_core::swap_exact_out_amounts (so requiredIn matches the chain), and
derives the slippage ceiling: { requiredInRaw, maxInRaw, priceImpactBps }.
no_pool and output_exceeds_liquidity (amount_out >= reserve) are returned as
errors. Read-only — no quoteHash; the on-chain max_amount_in is the real
guard.
The module swapExactOutQuote(tokenIn, tokenOut, amountOut, slippageBps)
method derives the pool via the config-free pool_id op, reads it, and wraps
the op in the { status, error, ... } envelope. Mirrors swapExactInQuote.
Not yet consumed by the QML swap view, so nothing breaks. Lets the buy field
stay editable when the SwapCard is rewired in a follow-up.
