Subject: [PATCH] fix(docker): resolve user creation conflicts and upgrade to
 CUDA 12.9

Fix critical Docker build failures and upgrade CUDA version for broader GPU support

User Creation Fix:
- Implement robust GID/UID 1000 conflict resolution with proper error handling
- Replace fragile `|| true` pattern with explicit existence checks and fallbacks
- Ensure appuser actually exists before chown operations to prevent "invalid user" errors
- Add verbose logging during user creation process for debugging

CUDA 12.9 Upgrade:
- Migrate from CUDA 12.8 to 12.9 base image for full RTX 50 series support
- Update PyTorch installation to cu129 wheels for compatibility
- Maintain full backward compatibility with RTX 20/30/40 series GPUs

Build Reliability Improvements:
- Make requirements.txt optional with graceful handling when missing
- Skip upgrading system pip/setuptools/wheel to avoid Debian package conflicts
- Add PIP_BREAK_SYSTEM_PACKAGES=1 to handle Ubuntu 24.04 PEP 668 restrictions

Architecture Support Matrix:
- RTX 20 series (Turing): Compute 7.5 - Supported
- RTX 30 series (Ampere): Compute 8.6 - Fully supported
- RTX 40 series (Ada Lovelace): Compute 8.9 - Fully supported
- RTX 50 series (Blackwell): Compute 12.0 - Now supported with CUDA 12.9

Resolves multiple build errors:
- "chown: invalid user: 'appuser:appuser'"
- "externally-managed-environment" PEP 668 errors
- "Cannot uninstall wheel, RECORD file not found" system package conflicts
