Both PRs independently modeled the same /mode/vs/0 Volume_*/Sleep_*
option tokens: #129 as beep/tropical_night_mode, #146 (already merged)
as buzzer_volume/good_sleep gated to the legacy ARTIK051 board
generation. They also each defined a helper named _option_token with
different return semantics (full token vs. value half) in
non-overlapping parts of the file, so git didn't flag it as a
conflict even though the second definition silently shadowed the
first.
Keep a single _option_token (value-half, the one already used by
buzzer_volume/good_sleep/spi/etc.), adjust beep's read/write to that
convention, and gate beep/tropical_night_mode off the legacy board so
they don't duplicate buzzer_volume/good_sleep on ARTIK051_KRAC-class
devices. Added a regression test locking in the gate.
