Audio: subsystem STATE sounds -- GaugeAlarm54 IS a StateIndicator; register Generator/Condenser/Reservoir state (task #50)

The audio subsystem binds AudioStateWatchers (class 28) to per-subsystem state
attrs (GeneratorState/CondenserState/ReservoirState) BY NAME.  Recovered the
watcher TYPE per attribute via a MakeObjectImplementation ClassID trace.

Root cause of the subsystem-state crash: the binary's 0x54-byte subsystem alarm
(FUN_0041b9ec, reconstructed as GaugeAlarm54) IS a StateIndicator -- its "three
sub-indicators" @0x18/0x2c/0x40 are the audio/video/gauge watcher SChains, and
level@0x14 is currentState.  The reconstruction had modeled that tail as an opaque
`_tail`, so the sockets were never constructed -> AddAudioWatcher AV'd on 0xCDCDCDCD.

- GaugeAlarm54: give it the three REAL, constructed SChainOf<Component*> sockets +
  AddAudioWatcher/Video/Gauge; SetLevel now fires the watchers on a level CHANGE
  (empty sockets = no-op, so the ~all other alarms are unaffected).  levelB (weapon
  LevelCountB "reset source") is left untouched -- weapons unchanged.  sizeof stays
  0x54 (static_assert holds -> SChainOf<Component*> is 0x14, layout exact).
- Register the state attrs -> the subsystem's own alarm (own AttributePointers[]
  chained to the parent): Generator.GeneratorState->stateAlarm, Condenser.
  CondenserState->condenserAlarm, Reservoir.ReservoirState->reservoirAlarm.  Those
  alarms are already SetLevel'd by the sim, so the state audio fires on transition.
- AudioStateWatcher guard now validates the +0x18 SOCKET (what AddAudioWatcher
  touches), not the +0 vtable -- GaugeAlarm54 is non-polymorphic at +0 (raw header)
  but has a real socket at +0x18.

audiostate skips 85 -> 10 (only AmmoBin AmmoState/SimulationState left).  The
Logical/Scalar/Enum subsystem attrs (ReportLeak/GeneratorOn/ConfigureActivePress/
MotionState/SpeedOfTorsoHorizontal/TargetRangeExponent) stay inert (read 0, silent,
non-crashing) -- they need backing members in size-locked layouts (a polish wave).
