docs: document Gemini Omni Flash 1.1 (GA) across Omni Flash pages

[lin-bot23]

Summary

Gemini Omni Flash 1.1 reached general availability on August 27, 2026 and is now the default model option in the ComfyUI node. The docs still described only the preview model. This PR:

• Overview page: adds the Omni Flash 1.1 capabilities (keyframe interpolation, reference to video with <IMAGE_REF_N> tags, scene extension up to ~40s, 360p/720p/1080p/4K output), a comparison table of Omni Flash 1.1 vs the preview model, and a resolution-based pricing table matching the partner node pricing page
• Workflow page: adds the five 1.1 workflows (t2v / i2v / r2v / edit / extend) with Comfy Cloud and download cards, preview videos, and sample asset cards
• Missing locales: the zh/ja/ko sites had no workflow subpage for Gemini Omni Flash (the overview pages still carried pre-split workflow content from an earlier page layout). This PR creates the three workflow subpages, adds the nav entries for all three languages, and rewrites the three overviews to match EN
• Notes the ComfyUI 0.34.2 minimum for the 1.1 workflows and the September 30, 2026 preview retirement date

Source

• Backend support: [Partner Nodes] feat(Google-Omni): add support for Omni 1.1 model ComfyUI#15929 (node GeminiVideoOmniV2, model options, resolution price badge)
• Workflow templates: Gemini Omni 1.1 Flash templates workflow_templates#1206 (api_google_gemini_omni_flash_1_1_{t2v,i2v,r2v,edit,extend}, minComfyUIVersion: 0.34.2)
• All preview/asset URLs HEAD-checked (200). The extend preview mp4 is not yet in the templates repo output/ folder, so that section uses the static webp only

Validation

• Heading/card/preview counts match across all 4 languages
• Frontmatter translation hashes synced via pnpm translate:sync-hash
• docs.json: one new nav entry per language, verified exactly once each, JSON valid
