Reopening CaloSurfaceStep extraction with material effects (draft)

[sophiemiddleton]

This pull request introduces calorimeter (Calo) geometry and surfaces into the KinKal geometry framework, enabling extrapolation and material modeling for the calorimeter disks. It adds the necessary data structures, construction logic, and configuration options to integrate the calorimeter with existing geometry and extrapolation tools. The most important changes are grouped below.

Calorimeter geometry integration

• Added a new Calo class in KinKalGeom to represent the calorimeter disks' geometry and surfaces, including construction from Calorimeter service parameters and accessors for all relevant surfaces (EMC_Disk_0/1_Inner/Outer/Front/Back) (KinKalGeom/inc/Calo.hh, KinKalGeom/src/Calo.cc) [1] [2].
• Integrated the Calo object into the main geometry (KinKalGeom) as a member, with accessor methods and construction in KinKalGeomMaker (KinKalGeom/inc/KinKalGeom.hh, GeometryService/inc/KinKalGeomMaker.hh, GeometryService/src/KinKalGeomMaker.cc) [1] [2] [3] [4] [5].

Surface enumeration and mapping

• Extended SurfaceIdEnum and the associated name mapping to include calorimeter disk surfaces and the EMC front panel, ensuring unique identification and lookup for all new surfaces (DataProducts/inc/SurfaceId.hh, DataProducts/src/SurfaceId.cc) [1] [2].
• Updated the surface mapping in MakeSurfaceSteps_module.cc to handle calorimeter disk surface virtual detectors (CommonMC/src/MakeSurfaceSteps_module.cc) [1] [2].

Configuration and extrapolation support

• Added calorimeter material and surface options to the FCL configuration files, enabling extrapolation to calorimeter disks and materials in various extrapolation modules (Mu2eKinKal/fcl/prolog.fcl) [1] [2] [3] [4] [5].
• Added new source files and build rules for the calorimeter geometry and extrapolation logic (KinKalGeom/CMakeLists.txt, Mu2eKinKal/CMakeLists.txt) [1] [2].

Other improvements

• Ensured explicit usage of KinKal::Disk to avoid ambiguity with other disk definitions (GeometryService/src/KinKalGeomMaker.cc) [1] [2] [3] [4].

These changes collectively provide the infrastructure and configuration needed for calorimeter-aware tracking and extrapolation in the KinKal framework.
