This makes the Omega(2012) resonance use the same PDG code and mass in O2DatabasePDG.h and in the Geant transport definition in O2MCApplication.cxx, and registers its antiparticle via AddAntiParticle instead of a duplicated AddParticle call. - O2MCApplication.cxx used 3335/-3335 and mass 2.012, now 123334/-123334 and 2.0125 to match O2DatabasePDG.h.

O2MCApplication.cxx's Geant transport definition versusO2DatabasePDG.h/PhysicsConstants.h. This aligns the transport-layer definition to the database values.O2DatabasePDG.hviaAddAntiParticleinstead of a duplicatedAddParticlecall, matching the convention used elsewhere in the file.
