feat(modules/amm): add the add-liquidity API and quoting

Introduce the add-liquidity vertical mirroring the swap + createPool patterns,
for depositing into an existing pool via the AddLiquidity instruction.

FFI (amm_ffi):
- add_liquidity_quote — decode poolData, orient the caller's max amounts to the
  pool's canonical order, run the guest's exact ideal->actual->delta_lp math, and
  return { amountARaw, amountBRaw, expectedLpRaw, priceRaw } in display order.
  Slippage-free like create's quote; the min-LP floor is applied at submit.
- add_liquidity_plan — canonicalize (token, max-amount, holding) as one unit,
  take vaults + LP definition from poolData, emit the 10-account AddLiquidity
  order (only the user holdings a/b/LP sign). Takes minLpRaw directly, like
  swap_exact_in_plan takes min_out.

Shared with createPool: extract canonical_triples (the pair/amount/holding
canonical swap) and plan_response (the tx-submission envelope); both the create
and add plans now use them.
