refactor: Centralize NX and environment configuration in config.py

MAJOR IMPROVEMENT: Single source of truth for all system paths

Now to change NX version or Python environment, edit ONE file (config.py):
  NX_VERSION = "2412"           # Change this for NX updates
  PYTHON_ENV_NAME = "atomizer"  # Change this for env updates

All code automatically uses new paths - no manual file hunting!

New Central Configuration (config.py):
- NX_VERSION: Automatically updates all NX paths
- NX_INSTALLATION_DIR: Derived from version
- NX_RUN_JOURNAL: Path to run_journal.exe
- NX_MATERIAL_LIBRARY: Path to physicalmateriallibrary.xml
- NX_PYTHON_STUBS: Path to Python stubs for intellisense
- PYTHON_ENV_NAME: Python environment name
- PROJECT_ROOT: Auto-detected project root
- Helper functions: get_nx_journal_command(), validate_config(), print_config()

Updated Files to Use Config:
- optimization_engine/nx_updater.py: Uses NX_RUN_JOURNAL from config
- dashboard/api/app.py: Uses NX_RUN_JOURNAL from config
- Both have fallbacks if config unavailable

Benefits:
1. Change NX version in 1 place, not 10+ files
2. Automatic validation of paths on import
3. Helper functions for common operations
4. Clear error messages if paths missing
5. Easy to add new Simcenter versions

Future NX Update Process:
1. Edit config.py: NX_VERSION = "2506"
2. Run: python config.py (verify paths)
3. Done! All code uses NX 2506

Migration Scripts Included:
- migrate_to_config.py: Full migration with documentation
- apply_config_migration.py: Applied to update dashboard

## Centralized Configuration
All NX and environment paths are now managed in `config.py`.
### To Update NX Version:
**OLD WAY** (required editing multiple files):
1. Edit `optimization_engine/nx_updater.py`
2. Edit `dashboard/api/app.py`
3. Edit `README.md`
4. Edit `docs/SYSTEM_CONFIGURATION.md`
5. Edit `.vscode/settings.json`
6. Search for other hardcoded paths...
**NEW WAY** (edit ONE file):
1. Open `config.py`
2. Change `NX_VERSION = "2412"` to your version (e.g., `"2506"`)
3. Done! All modules automatically use new paths.
### Configuration Variables
Import from `config.py`:
```python
from config import (
NX_VERSION, # "2412"
NX_INSTALLATION_DIR, # Path to NX installation
NX_RUN_JOURNAL, # Path to run_journal.exe
NX_MATERIAL_LIBRARY, # Path to physicalmateriallibrary.xml
NX_PYTHON_STUBS, # Path to Python stubs
PYTHON_ENV_NAME, # "atomizer"
PYTHON_ENV_PATH, # Path to Python executable
PROJECT_ROOT, # Project root directory
)
```
### Helper Functions
```python
from config import get_nx_journal_command
# Generate journal command automatically
cmd = get_nx_journal_command(
journal_script=Path("optimization_engine/import_expressions.py"),
prt_file,
exp_file
)
# Returns: "C:/Program Files/Siemens/NX2412/NXBIN/run_journal.exe" "..." -args "..." "..."
```
### Validation
```python
from config import validate_config, print_config
# Validate all paths exist
validate_config() # Raises FileNotFoundError if paths missing
# Print current configuration
print_config() # Shows all paths for debugging
```
### Files Migrated
- ✅ `optimization_engine/nx_updater.py` - Uses `NX_RUN_JOURNAL`
- ✅ `dashboard/api/app.py` - Uses `NX_RUN_JOURNAL`
- ⚠️ `.vscode/settings.json` - Manual update needed (VSCode limitation)
- ✅ `README.md` - References `config.py`
- ✅ `docs/SYSTEM_CONFIGURATION.md` - References `config.py`
### Testing Configuration
Run:
```bash
python config.py
```
Expected output:
```
================================================================================
ATOMIZER CONFIGURATION
================================================================================
NX Configuration:
Version: 2412
Installation: C:\\Program Files\\Siemens\\NX2412
...
```
### Future NX Updates
When NX 2506 (or any version) is released:
1. Edit `config.py`:
```python
NX_VERSION = "2506" # Changed from "2412"
```
2. Verify installation exists:
```bash
python config.py
```
3. Update VSCode stubs path in `.vscode/settings.json`:
```json
{
"python.analysis.extraPaths": [
"C:\\\\Program Files\\\\Siemens\\\\NX2506\\\\ugopen\\\\pythonStubs"
]
}
```
That's it! All Python code automatically uses NX2506.
