(FORK COMMIT) Increase TIS DB connection pool size

Addresses elevated 5xx server errors due to connection pool saturation during peak load times.

TIS RDS instance size allows up to 304 concurrent connections (default). We will increase the limit and monitor via cloudwatch to see how many of those are needed. Future performance tuning might allow a higher limit, but provide faster eviction of idle connections from the pool.
