fix(docker): override PEP 668 externally-managed-environment restriction

Browse Source 
Add PIP_BREAK_SYSTEM_PACKAGES=1 environment variable to allow system-wide 
pip installations in Ubuntu 24.04 container environment.

Ubuntu 24.04 includes Python 3.12 with PEP 668 enforcement which blocks 
pip installations outside virtual environments. Since this is a containerized 
environment where system package conflicts are not a concern, we safely 
override this restriction.

Resolves error: "externally-managed-environment" preventing PyTorch and 
dependency installation during Docker build process.
