Context

Roadmap item: P1 Error handling and resilience

Problem

get_db_client() in auth.py instantiates a new DatabaseClient on every call. This bypasses any connection pooling and will exhaust database connections under concurrent load.

What to do

  1. Create a module-level singleton DatabaseClient instance (or reuse the one already created in database.py / main.py).
  2. Update get_db_client() to return that shared instance.
  3. Ensure the instance is properly initialized at startup (e.g., via FastAPI lifespan) and closed on shutdown.

Acceptance criteria

  • Only one DatabaseClient instance is created per process lifetime.
  • Concurrent requests to auth endpoints share the same pooled client.
  • Existing auth tests still pass.
  • No regression in database connection behavior under pytest.

[Verification] All acceptance criteria met. Verified complete. auth.py implements a module-level singleton _db_client with init_db_client()/close_db_client() called from the FastAPI lifespan. database.py uses ThreadedConnectionPool (psycopg2) with configurable min/max connections. Closing as implemented.
