feat: Add Algorand (chainId 4160) for EIP-712 cross-chain account abstraction

[tasosbit]

Registers Algorand (non-EVM chain) with chain ID 4160 (0x1040) to support EIP-712-based cross-chain account abstraction per the Algo X EVM Accounts draft ARC.

This standard enables EVM wallets (e.g. MetaMask) to authorize Algorand transactions via ECDSA secp256k1 signatures verified by on-chain LogicSig programs on the Algorand side.

Notes:

• The linked ARC is in draft status but the chain ID assignment is required to be stable/final, as it is embedded in the EIP-712 domain and influences the abstracted account address derivation.
• Experimental EVM JSON-RPC-compatible endpoints and EIP3091-compatible explorers are in development but not stable enough to add here.

You successfully submitted a PR! Due to the amount of PRs coming in: we will only look at PRs that the CI is happy with. We can also not hold your hand getting the CI green - just look how others that where merged did it and RTFM. So as long as there is any CI check that reports an error - no human will look at this. You might be able to ask for some support after supporting the project - e.g. by sending funds to lists.eth. When you fixed things after a requested change - then you also need to (re-)request a review.
