fix: eliminate all 420 compiler warnings

- Add allow(async_fn_in_trait) in lib.rs for async trait methods
- Add integration_tests feature to Cargo.toml for cfg gating
- Gate trash_service_test module with cfg(feature = integration_tests)
- Remove unused MockFileWritePort from idor_protection_test.rs
