bitbox02: fix native cargo test
```
cd src/rust/bitbox02 && cargo test --all-features -- --test-threads 1
```
Failed because of a missing hex_lit feature.
What changed, and why it matters
This commit fixes a Rust build configuration issue so that the project's automated tests can run on a normal computer. It moves a required feature flag for the 'hex_lit' library from individual sub-crates to the shared workspace configuration. There is no indication this is a security fix or that it changes any runtime behavior on the actual BitBox02 device.
No security action required. Treat as a normal build/test maintenance commit.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The commit adjusts Cargo.toml dependency feature flags for the hex_lit crate. Previously, some crates explicitly enabled the ‘rust_v_1_46’ feature on their workspace hex_lit dependency, while the workspace root did not. This caused ‘cargo test –all-features’ in src/rust/bitbox02 to fail because the feature was missing at the workspace level. The fix enables ‘rust_v_1_46’ in the workspace root Cargo.toml and removes the redundant per-crate feature flags. This is a build/test tooling change only.
