docs: refresh localized documentation and Docker flags

[sophietao20-star]

Refresh the localized OpenMAIC documentation and align Docker/client feature-flag behavior with the current implementation.

• Synchronize configuration, deployment, getting-started, supported-models, and VoxCPM2 guidance across English, Simplified Chinese, Traditional Chinese, Japanese, Russian, and Arabic.
• Document Docker host-service access, ComfyUI SSRF requirements, provider configuration boundaries, parsing formats, persistence, and video export.
• Make NEXT_PUBLIC_ENABLE_PPTX_IMPORT consistently accept true/1 and add focused coverage.

Thanks for refreshing the Chinese documentation. I compared it against the actual registries, configuration paths, and deployment behavior. The built-in provider and model catalogs are accurate, but several gaps should be addressed before approval:

1. The Docker video-export profile starts the render service but does not compile NEXT_PUBLIC_ENABLE_VIDEO_EXPORT into the app, so the export entry remains hidden. The other documented NEXT_PUBLIC_* flags are also not exposed as Docker build arguments.
2. Custom OpenAI-compatible providers can currently be added through Settings, but not through arbitrary environment variables or server-providers.yml. Unknown server-side provider IDs lack providerType and fail during model resolution.
3. Docker users need explicit guidance for mounting server-providers.yml and connecting to host-side Ollama, Lemonade, VoxCPM, or ComfyUI services. localhost inside the container points to the OpenMAIC container.
4. ComfyUI setup, custom TTS/ASR providers, AliDocMind-only audio/video parsing and its supported formats, and NEXT_PUBLIC_ENABLE_PPTX_IMPORT are still missing from the Chinese docs. The unused BRAVE_API_KEY example should also be removed because Brave is keyless.

Please update the other localized documentation at the same time. It is fine to have the agent translate the finalized content consistently across languages.

Thanks, most of the previously reported gaps are now addressed. Three items remain before approval:

1. The corresponding English, Traditional Chinese, Japanese, Russian, and Arabic pages are still unchanged. Please have the agent propagate the finalized content across all localized documentation.
2. The documented host.docker.internal:8188 ComfyUI setup is still rejected by the production SSRF guard because comfyui-image is not server-managed. Please document ALLOW_LOCAL_NETWORKS=true for this topology, or add a server-managed ComfyUI configuration path.
3. The documentation says feature flags accept both true and 1, but NEXT_PUBLIC_ENABLE_PPTX_IMPORT currently checks only for the literal value true. Please align the implementation or narrow the documentation.

Thanks, the PPTX flag and ComfyUI SSRF guidance are now aligned with the implementation. One localization gap still remains: the latest commit translated only the newly added review-related snippets, rather than the full finalized documentation refresh.

For example, the non-Chinese supported-models pages still list older entries such as GPT-5.4 Mini and Qwen 3.6 while omitting the updated GPT-5.6, Qwen 3.7, Gemini 3.5, and other provider/model entries. The localized configuration pages are also still missing the Lemonade, video generation, default routing, feature flag, and server-option sections, while the localized deployment pages omit PostgreSQL persistence and MP4 export.

Please have an agent translate the complete finalized zh-cn refresh into English, Traditional Chinese, Japanese, Russian, and Arabic, while preserving environment variables, provider IDs, and model IDs exactly.

The documentation and localization gaps are now fully addressed. I verified that all five localized guide sets match the finalized Chinese structure, and that environment variables, provider/model IDs, commands, and code blocks remain consistent across languages.

The remaining blocker is the merge conflict with main in tests/config/feature-flags.test.ts. Please resolve it by retaining both the current main tests and the new PPTX feature-flag tests, then let the full PR checks run again.

All previously identified documentation, localization, configuration, and deployment gaps are resolved. The merge conflict was handled correctly and the full CI suite passes.
