Feat: add withdraw treasury fee script

[clauBv23]

Adds a Hardhat task (stg:propose:withdraw-treasury-fee) that reads a YAML config and proposes two batched transactions per entry to the Treasurer contract:

withdrawTreasuryFee(stargate, amountSD) — withdraws accrued fees from the Stargate pool to the Treasurer
transfer(underlyingToken, to, amountLD) — transfers the underlying token from the Treasurer to a recipient

The task automatically resolves the Stargate pool address from a TokenName (e.g. USDC), reads the underlying token address and decimals on-chain, and converts SD to LD for the transfer call.

Changes:

New task at devtools/tasks/treasuryFee/proposeWithdrawTreasuryFee.ts with YAML-driven config
Extended ITreasurer interface and Treasurer SDK with withdrawTreasuryFee and transferToken methods
Added Makefile target: make withdraw-treasury-fee (defaults to --onesig)

Usage: Edit devtools/tasks/treasuryFee/withdrawTreasuryFee.yml with chain, asset, amount (in shared decimals), and recipient, then run:

make withdraw-treasury-fee
