Betaflight Blackbox and debug: CLI settings

Blackbox logging device, sample rate and which fields are logged, plus `debug_mode`, which picks what the four debug channels record.

21 settings in Betaflight 2026.6. Each range and value list is read from the release's src/main/cli/settings.c, each default from the CLI get of the release built for the simulator (SITL), booted on an empty EEPROM, with no board config applied, so a board's own config can still change it. Set one with set name = value, then save. Paste a diff all into the CLI checker to test it against any release.

✓ present, Δ changed in that release (hover for what changed), — not in that release. “needs USE_…” is the build option the setting is compiled with: a cloud build without it has no such setting.
