Rename C++ component library to avoid Python module collision with Tracking directory

### Check duplicate issues.

- [x] Checked for duplicates

### Goal

The `TrackMerger` configurable relies on a generated Python module under the `Tracking` namespace (`Tracking.TrackingConf`). This causes an import failure when running frameworks like `ILDConfig` that have a local `Tracking/` directory on `sys.path`.

Python resolves `import Tracking` to `ILDConfig/StandardConfig/production/Tracking/__init__.py` instead of the CMake-generated Gaudi component package, shadowing `Tracking.TrackingConf`.

**Suggested Fix**
Rename the CMake library target in `k4RecTracker` (e.g., from `Tracking` to `k4RecTracker` or `k4RecTrackerTracking`) so that Gaudi exports configurables under a non-generic Python package name

**Error message:**
```bash
[k4run - WARNING] ConfigurableDb.getConfigurable: : Module Tracking.TrackingConf not found (needed for configurable TrackMerger)

### Operating System and Version

Ubuntu 24.04.4 LTS

### compiler

does not matter

### The version of the key4hep stack

nightlies 04.08.2026

### Package Version

from above nightlies

### Reproducer

```console
$ ipython
$ import sys, Tracking
$ print("Tracking package location:", Tracking.__file__)
Tracking package location: /home/user/code/ILDConfig/StandardConfig/production/Tracking/__init__.py
```
(This should be the `k4RecTracker` package...)

A reproducer of the bug when run the ILD Reco is available if necessary upon request

### Additional context

_No response_

Start by locating the CMake library target in k4RecTracker and inspect how it exports the generated Python configurable package. Reproduce the collision with the `ipython` import check and trace `Tracking/TrackMerging_FCCee.py` through `ILDConfig`'s `py_utils.py`. Done means the generated package has a non-generic import name and `TrackMerger` loads without the reported failure.
