feat(spike): add the M1 settings spike app and make targets

A separate throwaway app (own app ID, no permissions) that shows what the
Garmin Connect app delivers per settings field and writes values back, to
measure the undocumented settings limits on the real phone and watch.
Includes length-marked test strings, `make spike` / `make spike-sim`,
`make vectors`, and step-by-step instructions in docs/SETTINGS_SPIKE.md.
