🚀 feat(ui): isolate ratio configurations into dedicated “Ratio” tab and refactor settings components

Summary
• Added new Ratio tab in Settings for managing all ratio-related configurations (group & model multipliers).
• Created `RatioSetting` component to host GroupRatio, ModelRatio, Visual Editor and Unset-Models panels.
• Moved ratio components to `web/src/pages/Setting/Ratio/` directory:
  – `GroupRatioSettings.js`
  – `ModelRatioSettings.js`
  – `ModelSettingsVisualEditor.js`
  – `ModelRationNotSetEditor.js`
• Updated imports in `RatioSetting.js` to use the new path.
• Updated main Settings router (`web/src/pages/Setting/index.js`) to include the new “Ratio Settings” tab.
• Pruned `OperationSetting.js`:
  – Removed ratio-specific cards, tabs and unused imports.
  – Reduced state to only the keys required by its child components.
  – Deleted obsolete fields (`StreamCacheQueueLength`, `CheckSensitiveOnCompletionEnabled`, `StopOnSensitiveEnabled`).
• Added boolean handling simplification in `OperationSetting.js`.
• Adjusted helper import list and removed unused translation hook.

Why
Separating ratio-related settings improves UX clarity, reduces cognitive load in the Operation Settings panel and keeps the codebase modular and easier to maintain.

BREAKING CHANGE
The file paths for ratio components have changed. Any external imports referencing the old `Operation` directory must update to the new `Ratio` path.
