[Feature Request] add /multisig page

[0xbe1]

so that an account that holds MultiSig relevant resources could have this dedicated page to display signers, transactions etc

imho transactions can be rendered a bit differently for multisig because the pattern is quite fixed: create_transaction -> approve_transaction -> execute. would be great if they can grouped together to be extra clear

Example: https://explorer.aptoslabs.com/account/0x76ff3deac6723625606b11dfca7817fe1266fffcfc1fb26f5ccc9411f3def6fd?network=mainnet is a multisig account and transactions like https://explorer.aptoslabs.com/txn/2061940018?network=mainnet are multisig transactions but should be on overview (not just payload)
