ci: use vLLM 0.29 release image and align installation docs

Drop the old-base wheel reinstall and dependency repair block. Update source installation and configuration references to vLLM 0.29 while retaining explicitly matched 0.28 prebuilt Omni examples until its next release.

Validation: official image and CUDA/ROCm release artifacts checked; 6 documentation tests passed; diff whitespace checks passed. Markdown lint reports existing snippet/anchor issues. Container build not run: no builder available.
