LogiVoice: hide read-only parameter panels from the UI

Each LogiVoice module exposes both a state toggle and a read-only
parameters panel. The toggles are reliable, but the parameters panels
only partially decode the GetParameters response — fields not yet
identified surface as opaque hex blobs, which adds UI noise without
giving the user anything actionable (no write path either).

Stop registering the parameters classes in _LOGIVOICE_SETTINGS. The
state toggles still register and work as before. Bring the parameter
panels back when the wire encoding is fully reverse-engineered and a
write path lands.
