* Switch to using diff-cover for the Coverage gate
Enabling developers to check their PR coverage without waiting for CI
* Remove sonar-project.properties - in automatic mode Sonar will not read this file
* Add note to CONTRIBUTING.md
* Skip sonar in MQ
* Include tsx test files in common vite config
Otherwise we miss a bunch of the shared component tests
* Add storybook/preview-api to optimizeDeps
which is what vitest is telling me to do, which will hopefully stop
it flaking out.
