[ARM] Deploy 037 USD ARM (PYUSD/USDG) on mainnet

Record the on-chain execution of 037_DeployUSDARMScript: the USDC-quoted USD ARM
(MultiAssetARM) with PYUSD and USDG wired through their own PaxosAssetAdapter
proxies. Adds the 8 deployed contracts and the 037 execution entry to
deployments-1.json, and normalizes the 035 proposalId to a string.

Rename 037_DeployPaxosARMScript to 037_DeployUSDARMScript: the contract name, the
recorded deployment names (STABLES_ARM* -> USD_ARM*) and the ARM name/symbol
("Stables ARM"/"ARM-USDC-Stables" -> "USD ARM"/"ARM-USD"). The deployment logic
is unchanged.

Ownership of the ARM, its CapManager and both adapter proxies is handed to the
2/8 STRATEGIST multisig within _execute(), so there is no governance proposal and
the entry is recorded with proposalId 1 (NO_GOVERNANCE).
