chore: increase AZTEC_SLOT_DURATION (#8331)

Fixes #7850. 

Alters the aztec slot duration til 3 * ethereum slot duration = 36
seconds.

- Updated the sandbox to no longer ignore the `--l1-rpc-url` option, it
passed in test because they are all using the environment variables
`ETHEREUM_HOST`.
- Updated the watcher to check if running on an anvil with automine.
- Added a `watcher` to the sandbox, such that it can jump time if
automining as well. This was needed to work with `AZTEC_SLOT_DURATION >
ETHEREUM_SLOT_DURATION`.
- Moved the watcher into the `aztec.js` since it is now needed in
multiple places and it seeded to avoid a cycle, but needed to import
viem and l1-artifacts into it 😬
- Updates the `transfer.test.ts` to make multiple transfers in the same
blocks to speed up the test, as 36s blocks with 50 blocks is 30 minutes
which is longer than I would like to have that test run.
