style: apply cargo fmt so the release gate can run

The release gate's first real stage is `cargo fmt --check`, and it had
44 diffs across 15 files — enough to abort `create-release.sh` at step 0
before it touched a version number. Some of that drift is mine from the
last two days, some predates it in files I never opened
(bootstrap.rs, ghost_reaper.rs, openwrt/router.rs), and one is the
regenerated fips/app_ports.rs.

No behaviour change — rustfmt only.

Gate now: 8 of 9 green. The remaining red is cargo-test-weekly exiting
124, which is the 25-minute `timeout` expiring during a cold
CARGO_INCREMENTAL=0 rebuild on a loaded node — the tests never started.
Not a test failure.
