Issue #20: wire Mech BalanceCoolant (id 0x16) -- the auto-cooling-balance button

Browse Source 
Third instance of the silent-swallow pattern (unregistered handler id ->
Receiver NullHandler).  The Mech handler table @0x50BDF8 binds
{0x16, "BalanceCoolant" -> @0049f728}; the reconstruction never registered it.

Disasm-verified body (@0049f728): press-only guard (msg+0xc > 0; the binary
has NO novice lockout on this one), set EVERY condenser's valveState@0x1D0
to 1 (equal weights), then the shared redistribute @0049f788 -- which the
port ALREADY had faithfully as BTRecomputeCondenserValves (flow =
valve/total + condenserAlarm pulse; MoveValve calls it).  So the fix is:
- mech.hpp/mech.cpp: BalanceCoolantMessageID=0x16 + handler + MESSAGE_ENTRY
- heatfamily_reslice.cpp: BTBalanceCondenserValves bridge (Condenser is a
  complete type there; sets valves to 1 + redistributes)
- mech4.cpp: BT_BALTEST scripted harness (MoveValve press alternating with
  a Balance press)

VERIFIED headless (BT_BALTEST=1 BT_VALVE_LOG=1):
  boot     -> all valves 1, flows 0.1667 each
  MoveValve-> condenser#1 valve 5, flows 0.5 / 0.1x5 (the priority boost)
  BALANCE  -> all valves 1, flows 0.1667 each (equalized)
Awaiting the tester's live ADV-mode confirmation.
