style(fmt): rustfmt the GNOME 50 HDR files under the pinned toolchain

`feat(hdr): GNOME 50 HDR screencast capture` (0e977817) landed with rustfmt
drift — six files were not clean under the pinned 1.96.0 toolchain, so
`cargo fmt --all --check` (ci.yml "Format") is red on main. Pure whitespace/
wrapping from `cargo fmt --all`; no semantic change.
