Audio: KILL THE CHIRP -- ConfigureActivePress backed real (idle -1) on Sensor+Myomers (task #50)

The obnoxious always-on clicking was the cockpit CONFIGURE-MODE ticker: an
authored looped sequence gated by an AudioIntegerTrigger with threshold -1 on
<subsystem>.ConfigureActivePress (the held-configure-button index; -1 = none).
The attribute was one of the inert-pad redirects -- the pad reads 0 = "button 0
held forever" -> the ticker Start-fired at load and pulsed 2.7/s eternally.
Found via [sendcfg]/[seqstart] traces: the first seq start immediately follows
the trigcfg(thresh=-1, onID=Start) construction on the pad address.

Fix: real int configureActivePress = -1 APPENDED to Sensor ("Avionics") and
Myomers, registered in their attribute tables.  Both classes are byte-exact
factory allocs, so the sizeof locks AND the placement-new alloc constants are
bumped TOGETHER (Sensor 0x328->0x32C, Myomers 0x358->0x35C) -- the tripwire
caught a mid-layout insert (seekVoltage@0x330 shift) and a fixed-alloc overrun
before they shipped; member moved to the true tail.  Wiring the live value
(EnterConfiguration/ExitConfiguration sets/clears the index) restores the
authored hold-to-configure tick later; idle -1 is the correct silent state.

VERIFIED: ProgramButton01 plays ZERO times (was the 2.7/s chirp);
ConfigureActivePress binds real (vtbl=FFFFFFFF = the -1); FootFallInt at 0.98
gain; stable.
