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.

Test for both legacy and new events in bridges
