Cherry-pick of #17862 onto release/1.7.0. The commit is the merged main commit f16353af7a, picked with git cherry-pick -x --signoff.

Summary

Moves the CUDA vLLM image to vLLM v0.33.0 and vLLM-Omni v0.33.0rc1, with the compatibility changes and the vLLM sidecar structural-tag default from #17862. The CPU and XPU images keep their pins. This clears three bugs reported against 1.7.0-rc.0:

• DYN-5386: vllm-rs 0.32 reads every image as black; vLLM 0.33.0 fixes it (vllm#61586).
• DYN-5387: every LoRA load through vllm-rs 0.32 fails; vLLM 0.33.0 fixes it (vllm#63295).
• DYN-5388: Qwen3-TTS crashes at startup when stage 0 uses FlashInfer; Omni 0.33.0rc1 fixes the warmup (vllm-omni#9264), and the installer's Physis workaround keeps requests working on that backend.

The known issues are those listed in #17862: the CUDA image removes Omni's experimental Physis pipelines until vllm-omni#9939 is fixed, Omni video models still need the PyAV opt-in, LMCache's native ops do not load under torch 2.14, and the image pins Transformers 5.19.0.

Validation

• The pick applies without conflicts. git patch-id --stable gives the same ID for f16353af7a and for this commit: 398cc38a05.
• Since the branch cut, build(deps): pin AISim 0.14.0 RC0 sources for release/1.7.0 #18014 is the only release commit that touches files this PR changes (Cargo.lock, lib/bindings/python/Cargo.lock and pyproject.toml). They merge automatically, and cargo metadata --locked passes at the repository root and in lib/bindings/python.
• docs/fern/scripts/gen_llms_tables.py --check passes.
• pre-commit run on the 20 changed files passes. pytest-marker-report was skipped because it fails in the local environment on unchanged files too.
• On main, build(vllm): bump core to v0.33.0 and Omni to v0.33.0rc1 #17862 passed full CI at 6988c5c858, and its description lists the local GPU validation.
• Not run on this branch: image builds, GPU tests and the Rust tests (the local protoc 3.12 cannot build dynamo-llm). This PR's CI covers them.
