style: remove useAwait linting rule

[dreamorosi]

Summary

Changes

Please provide a summary of what's being changed

This PR removes the useAwait linting rule from the project because as discussed in the linked issue, it only added unneeded overhead. The PR also removes most - if not all - the setTimeout and Promise.resolve occurrences that were added because of this rule.

Finally, as part of working on the PR I ran npm run lint:fix on the project and several export orders changed as result. Similarly, I ran npm audit fix to remove a few CVEs from the dev environment rather than waiting for Dependabot to pick things up.

Please add the issue number below, if no issue is present the PR might get blocked and not be reviewed

Issue number: closes #5144

The Dependency Review CI check fails because of the yaml package having GHSA-48c2-rrv3-qjmp.

The package comes from multiple libs belonging to AWS CDK:

npm ls yaml
aws-lambda-powertools-typescript@0.0.1 /Users/aamorosi/Codes/aws-lambda-powertools-typescript
├─┬ @aws-lambda-powertools/testing-utils@2.32.0 -> ./packages/testing
│ ├─┬ @aws-cdk/toolkit-lib@1.19.1
│ │ └── yaml@1.10.3
│ └─┬ aws-cdk-lib@2.245.0
│   └── yaml@1.10.3
├─┬ lint-staged@16.4.0
│ └── yaml@2.8.3
├─┬ typedoc@0.28.18
│ └── yaml@2.8.3 deduped
└─┬ vitest@4.1.2
  └─┬ vite@8.0.3
    └── yaml@2.8.3 deduped

I tried manually updating them but nothing changed - since they're not related to this PR and are development dependencies, I'd recommend merging the PR anyway even though I don't like having a failing CI while doing it.
