chore: change interval to 30 seconds rather than every second

According to the Database Query Insights, this query was run in the backend over 20 thousand times in just the past hour alone (Almost 4 million requests in the past 7 days) and each request takes on average 1.8 seconds to make and the result is just always one row.

This PR hopes to lessen this bottleneck query by extending the interval for this query from every second to every 30 seconds.

Playwright tests seem to be failing because of a dependency on the database.

@roshaans Unit-tests fail for a completely different reason (snapshot mismatch), I don't understand how they used to pass, though 🤷‍♂️
