Subject: [PATCH] fix(reports): fix churn query crash and improve error
 reporting (#51)

The /api/reports/clients endpoint was crashing with a 500 on every request
because a raw JavaScript Date passed into a sql template literal in .having()
cannot be serialized by postgres-js. The fix serializes it as an ISO string
with an explicit ::timestamptz cast.

Also adds reportsRouter.onError() and improves the frontend error message
to surface which specific endpoint failed and why.

Fixes #49
