refactor: update tests with SignetStd for easy local/fork testing

[anna-carroll]

Refactor local tests to run against values in SignetStd contract, so that all local tests can be run as fork tests against any chain.

this is based on #83 ?

sorry, no - it's based on main. #83 history was messed up

nit: signet std could be immutables, but i don't think it matters

i made them mutable because of the pattern i used in the fork testing -- setting up the fork and then re-running setupStd(), so that it re-configures the vars based on the new chainid. if they're immutable and the test contract inherits Std, and Std sets itself up based on the chainid, then you need the correct chainid set at the time that the test boots up for Std to be properly configured.

i am actually realizing while writing this comment though that the fork testing strategy could be changed to

• do away with the fork/ folder implemented in feat: fork tests #86
• split these tests into host/ and rollup/ folders
• run them as unit tests with regular forge test
• run the exact same tests as fork tests with forge test --match-path rollup/ --fork-url $ROLLUP_RPC / same for host

(which is cool 👀)

nevertheless i think having the configuration mutable leaves things a bit more flexible re: setting up forking in the code? 🤔
