feat(miner): remove batch balancer-related functionality

Proposed Changes

Removed BatchPreCommitAboveBaseFee, AggregateAboveBaseFee, and the related checks.

The MinCommitBatch is actually constrained by the SNARK circuits, so it will remain at 4 without change:

• You need 4 or more sectors to ensure that the verification time for aggregated proofs is smaller than for batched proofs.

• You need 13 sectors or more to ensure that the aggregated proof size is smaller than the batched proof size.

The MaxCommitBatch limit comes from the original (FIP-0013), and it seems there's not much incentive to modify it, so these two parameters will remain unchanged.

@tediou5 : no pressure, but is this ready for review? If so, lets move it out of draft to make it clear. Thanks.

@BigLep Got it, let me check the part of aggregation.

[tediou5]

@BigLep Yes, I think it's ready for review now. I'd like to get some feedback as well since I'm not very familiar with this part of the code, and I'm a bit worried I might have missed something.

Please run make gen and commit the results.

Also, this appears to now be submitting batches that are too large (See the failing tests):

batch of 1000 too large, max 256

I think this is the max batch size for precommit?
