fix: Do not reuse anvil admin key

[spalladino]

In #8277 we added a PUBLIC_API_KEY that was used for accessing anvil with cheat codes disabled, and the API_KEY was left for "admin" access with cheat codes allowed. However, the API_KEY is also needed for connecting to the node, which is is needed for retrieving proofs, needed for prover nodes to operate.

This PR changes how keys are handled. API_KEY is now mapped to the anvil public access, so it is not disclosed when sharing access to the node API. A new FORK_ADMIN_API_KEY is introduced for admin access, and only used for bootstrapping operations and for the bootstrapping sequencer.

Benchmark results

Metrics with a significant change:

• avm_simulation_time_ms (FeeJuice:set_portal): 14.6 (+31%)

Detailed results

All benchmarks are run on txs on the Benchmarking contract on the repository. Each tx consists of a batch call to create_note and increment_balance, which guarantees that each tx has a private call, a nested private call, a public call, and a nested public call, as well as an emitted private note, an unencrypted log, and public storage read and write.

This benchmark source data is available in JSON format on S3 here.
