ctp: delete hardhat drippie tests

contracts-periphery: foundry tests for drip checks

Add foundry tests for the dripchecks. Each test suite
includes a fuzz test for the positive and negative cases.
This is a continuation of porting all contracts tests
to foundry for a unified developer testing environment.

feat(ctp): audited Drippie mainnet deployment

The foundry tests merged in https://github.com/ethereum-optimism/optimism/pull/4760
are a superset of the hardhat tests so we can delete the
hardhat drippie tests in favor of the foundry based tests.
This is moving us closer to a unified smart contract
development environment where we can enforce the same standards
across all smart contracts developed in the monorepo.

ctp: add foundry tests for Drippie

op-batcher: Simplify configs, dedup init, & simplify init code

allow body parser options to be passed in

maint(ctb): clean up Hashing tests

op-node: ensure sequencer selects L1 origin within sequencer time drift and use conf depth util

and use conf depth util

This commit adds foundry tests for the `Drippie` smart contract.
Test coverage is improved as additional events that were not tested
before are now being tested for. Also allows a future version of
`Drippie` to be more easily invariant tested.

All hardhat tests are ported 1:1 with additional assertion of
specific `CALL`s and events being emitted.

This uses the same op-services/crypto signer initialization. It also
simplifies the batcher struct and config.

maint(ctb): clean up various test files

Cleans up various test files and updates them to the new format.

Cleans up tests for Hashing.sol and uses new format.
