Issue #31: wire the EJECT button (EjectAmmo msg 0xb @004bb9b8) -- the in-mission unjam

Browse Source 
Disasm-faithful transcription of the export-gap handler onto
ProjectileWeapon (MESSAGE_ENTRY id 0xb, the #19 pattern).  PRESS arms
the ~3s UpdateEject countdown (bin alarm -> Ejecting(3); gate 2 parks
the weapon offline mid-eject -- authentic).  HOLD to completion =
DumpAmmo jettisons the bay -> NoAmmo.  TAP (release early) cycles ONE
round out via FeedAmmo and returns the weapon to Loading -- clears a
jam at the cost of a round (and recovers a FailureHeat 7 while rounds
remain).  Binary structure kept exactly incl. the press-no-bin
fall-through into the release block.

AmmoBin: Ejecting(3)/Ejected(4) alarm levels decoded + named
SetAmmoState accessor (databinding rule).  Always-on forensics:
'[weap] EJECT tap' + '[ammo] bay DUMPED overboard (N rounds)'.

Rig-verified live (BT_EJECTTEST=1 / =hold on LRM15): taps eject one
round each and return the weapon to service (15->8 across cycles);
hold dumps all 16 -> NoAmmo.  Awaiting a human press of the actual
ENG-page button on a jammed weapon.
