feature: integrate Monad & Sonic

[TheDivic]

📖 Context

Type of change

• Non-breaking change (backwards compatible)

Why are we doing this?

• Two new chain integrations (both broken unfortunately atm, until we get a response from the chain developers).
• Code needed some refactoring to figure the bugs encountered during integration

What did we do?

• Integrated (but disabled) Monad testnet, Sonic Mainnet & Sonic Blaze testnet
• Some refactoring applied while debugging and working on these integrations, especially in the API layer.

How Has This Been Tested?

• Monad works only for smart account creation, otherwise it will throw an error because the sender is not entrypoint, and we can't set the EP as sender or the RPC will throw sender not eoa. Waiting for fixes from the Monad team.
• Sonic RPC still throw a gas error when calling eth_estimateGas. Waiting for fixes from the Sonic team.
