Betaflight Servos and gimbal: CLI settings

Servo output rate and centre, servo tilt, and the gimbal head-tracking settings newer releases add.

23 settings in Betaflight 2026.6. Each range and value list is read from the firmware's settings.c, each default from the CLI get of the release built for the simulator (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.
