fix: gas limit estimation

[matthewwalsh0]

Explanation

Prevent the following error when estimating gas limits on specific chains:

invalid argument 0: json: cannot unmarshal hex number with leading zero digits into Go struct field TransactionArgs.gas of type hexutil.Uint64

Specifically:

• Remove the calculated fallback gas property from the eth_estimateGas request.
• Remove all gas fee properties (gasPrice, maxFeePerGas, maxPriorityFeePerGas) from the eth_estimateGas request.
• Calculate fallback gas, max gas limit, and buffer using fractions rather than decimals.

• FIXED: Gas limit estimation on new transactions and via estimateGas and estimateGasBuffered methods.
