feat(firmware): validate configuration and migrate sensor-driven flight APIs

Validate configuration through its owning schemas and keep board
declarations separate from shared F722 resource ownership. Bound USB
transitions, isolate transport failures and retain restart-only activation.

Migrate navigation and flight consumers with the sensor and schema
contracts. Require explicit installation data and synchronous output
authority; board motor outputs remain inhibited.

Validation: assembled-prefix host tests, strict Clippy, platform/USB tests
and both ARM release builds. Final-source coverage and scoped Miri/Kani
evidence are retained separately from hardware qualification.
