test(maintenance): switch layers to vitest

[dreamorosi]

Summary

Changes

Please provide a summary of what's being changed

This PR moves the unit and end to end tests for the layers package to use vitest as test runner.

This action is part of the ongoing migration from Jest to Vitest, and all the changes in the tests focus on changing the imports and using Vitest-specific APIs and rewording the test headers.

The PR includes a minor change to the TestInvocationLogs.doesAnyFunctionLogsContains() method which now accepts regexes as well as strings for the needle to find in the haystack. This simplifies slightly the tests for the layers while maintaining backwards compatibility.
