Simplify naming of sim_telarray configuration files written to disk for simulation production.

[GernotMaier]

Simplify naming of sim_telarray configuration files written to disk for simulation production:

• telescope configuration files are now of type CTAO-LSTS-01.cfg, CTAO-SSTS-25.cfg
• array configuration files are of type CTAO-South-beta.cfg
• added a run directory level to model, such that e.g. we get

tree -d simtools-output
simtools-output
├── corsika
│   ├── run000010
│   └── run000011
├── model
│   ├── run000010
│   │   └── 7.0.0
│   └── run000011
│       └── 7.0.0
├── multi_pipe
│   ├── run000010
│   └── run000011
├── sim_telarray
│   ├── run000010
│   └── run000011
└── sub

This will allow to run in future a paralellization of some applications (e.g., multi-light-level flasher simulations did overwrite configuration files).

Raises an exception if existing configuration files are overwritten by an application.

Note! Basic assumption is that configuration files are written once into the same directory by an application.

Note that this removes changes introduced in PR #2287.

Pull request overview

This PR updates sim_telarray configuration handling in simtools by simplifying on-disk config filenames (switching to CTAO-*.cfg) and introducing run-number subdirectories under model/ to prevent configuration collisions across runs, with corresponding updates to output validation and test resources.

Changes:

• Simplify sim_telarray telescope/array configuration filenames to the CTAO-...cfg scheme and update code paths that reference these files.
• Add a run-number directory level for model outputs (e.g., model/run000010/<model_version>/) and update output validation accordingly.
• Add overwrite protection for array config writing and refresh unit/integration tests plus generated reference configs.
