[wallet/desktop] feat: add multisig toggle to allow/disallow signing multisig transactions from unknown accounts

[OlegMakarenko]

Problem

The current set of measures is insufficient to protect users from multi-signature scam transactions.

Current behaviour

Wallet presents a cosignature form explaining the risks of signing multi-signature transactions from unknown accounts.

Solution

• Disallow signing multisig transactions from unknown accounts by default.
• Present warning instead.
• Added the advanced settings section with "toggle" (dropdown) which can turn on/off this security protection.
