r4bbit cd8a84374b refactor(amm): extract swap-input formula into amm_core ...

Lift the inverse constant-product SwapExactOutput math out of the guest's
exact_output_swap_logic into amm_core::swap_exact_out_amounts(amount_out,
reserve_in, reserve_out, fee_bps) -> Option<(effective_in, required_in)>:
ceil(reserve_in * amount_out / (reserve_out - amount_out)) lifted through the
fee via mul_div_ceil. exact_output_swap_logic now calls it and keeps its
nonzero/exceeds-reserve asserts. Behavior-preserving (the panic-message tests
still pass); None (out >= reserve or zero fee multiplier) surfaces as the
existing expect.

Makes the on-chain exact-output pricing one reusable function so the
off-chain quote can produce byte-identical required-input figures instead of
re-deriving the inverse formula. Mirrors swap_exact_in_amounts.
