Fix Buffer size setting never being applied; add Safety Switch control type
- Buffer size (samples) in Settings > Acquisition was captured into the
settings dict but never read anywhere — SignalBuffer always used the
hardcoded MAX_BUFFER=20_000 constant (which happens to match the
dialog's default, hence it looking like the value "reverts"). Add
AcquisitionEngine.set_buffer_size(), wired in on startup and on Settings
apply; existing buffers are rebuilt at the new size in place, keeping
their most recent samples.
- New "Safety Switch" control type: an On/Off Switch that's disabled
outright until acquisition is running, with a lock icon shown while
disabled. AcquisitionEngine gains a run_state_changed(bool) signal
(emitted from start()/stop()); ControlWidget gains a
_check_safety_lock() hook (no-op by default, called uniformly by
ControlPanel on every widget) that SafetySwitch overrides. engine is
now threaded through to every ControlWidget for this. Persists via
ControlSpec.control_type alone — no schema change needed.
