Fix Pydantic V2 deprecation warnings and requirements compatibility

[Copilot]

Fixed critical errors in the repository that were preventing proper functionality with Python 3.12 and modern Pydantic versions.

Status

Successfully fixed all errors and warnings in the codebase:

• ✅ Fixed Pydantic V2 deprecation warnings
• ✅ Updated requirements.txt for Python 3.12 compatibility
• ✅ All 15 tests passing
• ✅ No security vulnerabilities found

Changes Made

1. Pydantic V2 Compatibility (dlplus/config/settings.py)

• Updated to use modern ConfigDict instead of deprecated Config class
• Removed deprecated env parameter from all Field definitions
• Environment variables are now properly read using Pydantic V2 conventions

2. Requirements Compatibility (requirements.txt)

• Fixed torch version incompatibility (was 2.1.1, now >=2.2.0,<3.0.0 for Python 3.12 support)
• Changed from strict version pinning (==) to compatible release specifiers (~=)
• This prevents breaking changes from major version updates while allowing safe patches and minor updates

Testing

• ✅ All 15 tests passing
• ✅ Server starts without errors
• ✅ No deprecation warnings
• ✅ Code review passed with no issues
• ✅ CodeQL security scan found 0 vulnerabilities

The repository is now fully functional with Python 3.12 and modern dependencies.
