Add #![deny(clippy::unwrap_used, clippy::expect_used)] to database, ml-data,
trading-data, and broker_gateway_service crates, fixing all violations:
- database/src/transaction.rs: replace 7x .expect("Transaction already consumed")
with .ok_or_else(|| DatabaseError::Transaction) and 2x .unwrap() on take()
in commit/rollback with safe .ok_or_else() variants
- ml-data/src/performance.rs: replace .last().unwrap() and .first().unwrap()
with if-let destructuring pattern
- trading-data/src/positions.rs: replace 3x write!().unwrap() with let _ = write!()
and Decimal::from_str_exact("0.02").unwrap() with Decimal::new(2, 2)
- trading-data/src/executions.rs: replace 3x write!().unwrap() with let _ = write!(),
and 3x .expect() on and_hms_opt(0,0,0) with .unwrap_or_default()
- broker_gateway_service/src/main.rs: replace encode().unwrap() with if-let,
and from_utf8().unwrap() with .unwrap_or_else()
- Add #[allow(clippy::unwrap_used)] to test modules in all affected crates
