fix: bulk fund wallets with massive amount

[SakuBoyz]

Description

Rearranged the code to generate wallets before deploying the Funder contract. The contract is now funded based on the number of wallets generated. The total fund amount is calculated by multiplying the per-wallet funding amount by the number of addresses. This ensures the contract has enough Ether to fund all generated wallets.

Testing

Now we can bulk funding wallets more than 1_000 ETH

lgtm, thanks for the fix

without the fix: the Funder contract balance is hardcoded to 1000 ETH while it requires 100 000 ETH to fund all the wallets so the call reverts.

$ polycli fund -a 100 -n 1000 --verbosity 500

with the fix: the Funder contract is funded with just the right amount of ETH to fund all the wallets.
