Adds check=AsyncConnectionPool.check_connection to detect and discard dead connections before use (equivalent to pool_pre_ping=True), and max_lifetime=300 to recycle connections older than 5 minutes (equivalent to pool_recycle=300). This fixes SSL connection closure errors on NeonDB's free tier. Co-authored-by: MattiaFailla <11872425+MattiaFailla@users.noreply.github.com>
