fix: update all vulnerable dependencies (Dependabot alerts)

Critical:
- torch 2.1.0 → 2.6.0 (RCE via torch.load, heap overflow, use-after-free)

High:
- transformers 4.36.0 → 4.53.0 (deserialization, ReDoS, input validation)
- cryptography 41.0.7 → 44.0.1 (subgroup attack, null pointer - linux/windows)
- Pillow 10.x → 11.1.0 (buffer overflow, PSD out-of-bounds write)
- python-multipart → 0.0.22 (arbitrary file write, ReDoS)
- scikit-learn 1.4.0 → 1.5.0 (sensitive data leakage)
- starlette 0.35.1 → 0.46.2 (DoS via multipart, in lock file)

Applied to: requirements.txt, requirements-linux.txt,
requirements-windows.txt, requirements-lock.txt, Dockerfile
