[Bug]: database is locked when running dashboard

Describe the bug

When the dashboard is running, openadapt.record fails:

We would like to be able to create recordings using the tray icon or the command line while the dashboard is running.

To Reproduce

python -m openadapt.app.dashboard.run

In a separate shell:
python -m openadapt.record foo
