bitbox02-sys: sort allowlists
What changed, and why it matters
This commit simply alphabetically sorts three lists of C function, variable, and type names that the Rust build process is allowed to reference. No names were added or removed, only reordered. It has no effect on device behavior or security.
No action required; this is a non-security cosmetic/refactoring commit.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The change is a pure refactor in src/rust/bitbox02-sys/build.rs. The bindgen allowlists (ALLOWLIST_VARS, ALLOWLIST_TYPES, ALLOWLIST_FNS) are reordered alphabetically. The diff shows only line moves; the same set of identifiers remains present. There is no functional change to generated bindings, firmware logic, or attack surface.
