add new price provider with base asset

[shivam-ef]

Note

High Risk
High risk because it introduces a new price provider implementation and an on-chain upgrade/config bundle that changes how token prices are sourced and converted, impacting collateral/borrowing and liquidation logic.

Overview
Introduces PriceProviderV2, replacing per-asset booleans with a configurable baseAsset field so tokens can be priced in arbitrary base assets (e.g., ETH/BTC/EUR) and converted to USD at read time; adds base-asset bookkeeping plus stricter config validation and safe removal controls.

Adds a Gnosis Safe upgrade script and generated transaction bundle to upgrade the existing PriceProvider proxy to V2 and set configs for 19 OP mainnet tokens (including a new liquidEUR), and updates OP deployment configs/fixtures to include liquidEUR support and switch sethfi to an accountant oracle.

Stale output JSON uses wrong sethfi oracle configuration

High Severity

The committed output/UpgradeToPriceProviderV2.json transaction bundle doesn't match the current script. The old sethfi Pyth oracle (0x8454985aA5bc30162aC258D3CCf89E9BA6604d99) is present in the output, while the new accountant oracle (0x05A1552c5e18F5A0BB9571b5F2D6a4765ebdA32b) defined as SETHFI_ORACLE in the script is completely absent. The output was generated from a prior script version where sethfi used a Pyth oracle without a base asset, rather than the current accountant oracle with ETHFI as baseAsset. If this Gnosis Safe transaction bundle is submitted as-is, sethfi would be configured with the wrong oracle type, wrong decimals (16 vs 18), and no base-asset conversion.
