eventdb uses local SQLite even when PostgreSQL is configured

[yubin-lin1996]

Describe the problem

When deploying the self-hosted NetBird management service in a Kubernetes environment, and configuring PostgreSQL as the storage backend (via NETBIRD_STORE_TYPE=postgres and NETBIRD_STORE_ENGINE_POSTGRES_DSN=...), the main database works correctly with PostgreSQL.

However, even in this setup, a local event.db SQLite file is still created inside the management container's filesystem. This suggests that the event database (eventDB) does not follow the same configuration and silently defaults to SQLite.

This behavior becomes problematic in production Kubernetes deployments, where container filesystems are ephemeral. As a result, whenever the manager Pod is restarted, the event.db file is lost, and with it, any events or logs stored in it. This leads to a loss of observability and historical data, which is critical for auditing and debugging purposes in production environments.

To Reproduce
Deploy netbird/management with NETBIRD_STORE_TYPE=postgres and NETBIRD_STORE_DATA_SOURCE set correctly.

Start the pod and verify PostgreSQL is used.

Observe that a local event.db file is still created in the container.

Logs do not indicate a switch to PostgreSQL for event storage.
