chore: add scripts to upgrade all coverage contracts

[evercoinx]

Note

Medium Risk
Adds new orchestration scripts that generate/broadcast upgrade and role-grant transactions for multiple mainnet proxies via Timelock and for Sepolia in a single admin tx; incorrect usage/order could mis-upgrade proxies or leave critical wiring/roles unset.

Overview
Adds end-to-end Forge scripts to upgrade all Coverage UUPS proxies and perform required post-upgrade wiring.

On Ethereum mainnet, UpgradeAllCoverageEthereum.s.sol deploys new implementations, then prints Safe Timelock scheduleBatch/executeBatch calldata for a 13-call batch (upgrades, Swapper.setClaimManager, ClaimManager.initializeV2, and PAUSER_ROLE grants), plus a separate multisig call to CoverPoolFactory.setCoverPoolImplementation.

On Sepolia, UpgradeAllCoverageSepolia.s.sol performs the full upgrade+wire+role-grant sequence in one broadcast transaction, and new VerifyEthereumConfig.s.sol plus updates to VerifySepoliaConfig.s.sol add on-chain configuration checks (including Swapper.claimManager, ClaimManager V2 init state, and optional PAUSER_ROLE validation).
