Add tritonBLAS as dependency

[Copilot]

tritonBLAS now supports proper pip install. Add it as a dependency and remove manual installation from CI/container configs.

Changes

• pyproject.toml: Added tritonblas as git dependency pointing to commit d0b4a6b (includes pip install fix from tritonBLAS#58)
• CI scripts: Removed manual cloning/installation from run_tests.sh and run_perf_benchmark.sh
• Workflows: Removed manual installation from iris-external-validation-test.yml
• Containers: Removed manual installation from docker/Dockerfile and apptainer/iris.def

Notes

• Upgraded from commit 47768c9 to d0b4a6b to use version with proper package discovery
• Removed TRITONBLAS_PATH environment variable from Apptainer (no longer needed)
• Net reduction: 81 lines of installation code → 1 line dependency declaration

[Copilot]

The TRITONBLAS_PATH environment variable was removed from the %environment section (line 42) and from PYTHONPATH, but it's still being set in the %post section at line 11 of the file. For consistency, line 11 should also be removed since tritonBLAS is now installed as a regular pip dependency and doesn't need a dedicated path.
