feat: add limit on aggregator spending

[uri-99]

This PR

• This PR adds to the Batcher the ability to set a max_fee_allowed_to_respond.
  • This variable is currently being set in lib.rs as MAX_FEE_FOR_AGGREGATOR_MULTIPLIER , where it is used to multiply it to fee_for_aggregator, to get the max_fee_allowed_to_respond.
• Aggregator can't spend more fee than what was set in max_fee_allowed_to_respond , to respond that task

To Deploy

This PR changes no memory, so a normal upgrade must be run for both AlignedLayerServiceManager and BatcherPaymentService.

To Test

Happy Path

make anvil_start_with_block_time

make aggregator_start

make operator_register_and_start

make batcher_start_local

make run_explorer

And when they finish starting up, you can send proofs:

make batcher_send_risc0_burst

Playing around max_fee_allowed_to_respond

For this you can do, for example:

• change the MAX_FEE_FOR_AGGREGATOR_MULTIPLIER to different values and check it behaves accordingly
• change/hardcode maxFeeAllowedToRespond values on the BatcherPaymentService and check it behaves accordingly.
• change/hardcode maxFeeAllowedToRespond values on the AlignedServiceManager, and check it behaves accordingly.

just refactors, I think code looks good, need to test thoroughly

More info regarding this, doing a cast send does not fix this issue. I think the cause of this is that the batcher payment service needs to have balance and not the batcher itself.

I had to change the multiplier to 1 for some batches to get it started. This gives it some balance for it to have enough for the 2x multiplier.

Possible solution to this is adding a method on the batcher payment service to fund itself on the aligned service manager (which would basically be a transfer from contract to contract).

@taturosati
Added deposit funds to AlignedLayerServiceManager in make anvil_deploy_aligned_contracts .
No new function was needed to implement this, the existing depositToBatcher(address) was used
