Split tests for `client/handlers/vaults.test.ts`

[aryanjassal]

Specification

Due to a resource leak crashing the CI, all the tests needed to be grouped. Right now, all the VaultsSecrets and Vaults RPC handlers are being tested in the same file. As a single file cannot be run concurrently, running the entire file is taking up to 3 minutes. It is also making the tests difficult to view/modify/debug.

As such, the tests need to be split into individual files as before. This will help speed up the CI too, as the tests will finish quicker.

Additional context

Tasks

1. Split each describe block from client/handlers/vault.test.ts into its own file
2. Resolve the resource leak which was crashing the CI

ENG-456 Split tests for `client/handlers/vaults.test.ts`

[aryanjassal]

There are tests which test multiple domains at the same time. Specifically, the tests for vaultsSecretsNew, vaultsSecretsDelete, and vaultsSecretsGet are all in the same describe block, which makes ensuring full coverage of tests challenging.

These tests should be broken up into separate describe blocks. And instead of using the RPC to make/get/delete files, we can use the VaultOps methods to do so. Doing it this way will introduce more isolation and allow for better test writing.

This is being addressed in Polykey#838.

While it would take longer, many RPC handlers like VaultsSecretsGet can be easily tested using fastcheck. This should be done when separating and cleaning up the tests.

This PR is for splitting the tests... right? Generally splitting is good. You should find out WHY splitting is not possible and that is a code smell. So we don't want to needdlessly group tests that don't need to be grouped unless they are sharing a resource of some sort that you need to synchronize access to. But even then it's best that this is not an issue.

Currently, the file has gotten to around 5000 lines long. None of the tests run in parallel, so the file is very slow compared to other tests. This is becoming more and more of an issue as time goes past and new commands are added.

Ideally, I want to split the tests into their own files before I start implementing the VaultsSecretsCopy and VaultsSecretsMove commands, as they would blow up the size by a significant amount. While this is not critical to Polykey's functionality, it is still critical to Polykey's development workflow.
