refactor(core): drop unreachable hotkey dtor and dedupe tray predicate

Remove impl Drop for Hotkey: the instance lives in a OnceLock static via
the singleton! macro and is never dropped; exit-time unregistration is
already handled by Hotkey::reset().

Spell the include_proxy_groups/display-mode predicate identically at
both evaluation sites in tray menu building; behavior is unchanged
(Option != Some("disable") is equivalent to unwrap_or("default") != "disable").
