✨ refactor: Restructure model pricing components and improve UX consistency

- **Fix SideSheet double-click issue**: Remove early return for null modelData to prevent rendering blockage during async state updates
- **Component modularization**:
  - Split ModelDetailSideSheet into focused sub-components (ModelHeader, ModelBasicInfo, ModelEndpoints, ModelPricingTable)
  - Refactor PricingFilterModal with FilterModalContent and FilterModalFooter components
  - Remove unnecessary FilterSection wrapper for cleaner interface
- **Improve visual consistency**:
  - Unify avatar/icon logic between ModelHeader and PricingCardView components
  - Standardize tag colors across all pricing components (violet/teal for billing types)
  - Apply consistent dashed border styling using Semi UI theme colors
- **Enhance data accuracy**:
  - Display raw endpoint type names (e.g., "openai", "anthropic") instead of translated descriptions
  - Remove text alignment classes for better responsive layout
  - Add proper null checks to prevent runtime errors
- **Code quality improvements**:
  - Reduce component complexity by 52-74% through modularization
  - Improve maintainability with single responsibility principle
  - Add comprehensive error handling for edge cases

This refactoring improves component reusability, reduces bundle size, and provides a more consistent user experience across the model pricing interface.
