What does this PR do?

Updates Mocha-based test execution to use --allow-uncaught so uncaught exceptions are no longer absorbed by Mocha and instead fail fast by propagating to the process. This change applies to the repo's Mocha test scripts in package.json and to a direct Mocha invocation in .github/workflows/platform.yml that does not go through those scripts.

Motivation

Ensure errors do not go unnoticed.

Add --allow-uncaught to mocha-based test scripts in package.json so
uncaught errors are treated as fatal instead of being absorbed by mocha.

Update the direct mocha invocation in platform.yml to match script behavior
for CI jobs that do not go through npm/yarn test scripts.

Please move this option into the mocharc file. That way we only need to list it once instead of on each script

Configure allowUncaught in .mocharc.js and remove duplicated
--allow-uncaught flags from test scripts and workflow invocation.
This keeps mocha behavior consistent while reducing script noise.
