chore: fix various e2e test setup issues (#12670)

I noticed a few issues when running e2e tests that will be resolved by this PR: - Most important: for some test suites (fields, fields-relationship, versions, queues, lexical), the database was cleared and seeded **twice** in between each test run. This is because the onInit function was running the clear and seed script, when it should only have been running the seed script. Clearing the database / the snapshot workflow is being done by the reInit endpoint, which then calls onInit to seed the actual data. - The slowest part of `clearAndSeedEverything` is recreating indexes on mongodb. This PR slightly improves performance here by: - Skipping this process for the built-in `['payload-migrations', 'payload-preferences', 'payload-locked-documents']` collections - Previously we were calling both `createIndexes` and `ensureIndexes`. This was unnecessary - `ensureIndexes` is a deprecated alias of `createIndexes`. This PR changes it to only call `createIndexes` - Makes the reinit endpoint accept GET requests instead of POST requests - this makes it easier to debug right in the browser - Some typescript fixes - Adds a `dev:memorydb` script to the package.json. For some reason, `dev` is super unreliable on mongodb locally when running e2e tests - it frequently fails during index creation. Using the memorydb fixes this issue, with the bonus of more closely resembling the CI environment - Previously, you were unable to run test suites using turbopack + postgres. This fixes it, by explicitly installing `pg` as devDependency in our monorepo - Fixes jest open handles warning
