♻️ refactor: Extract scroll effect logic into reusable ScrollableContainer component

- Create new ScrollableContainer component in @/components/common/ui
  - Provides automatic scroll detection and fade indicator
  - Supports customizable height, styling, and event callbacks
  - Includes comprehensive PropTypes for type safety
  - Optimized with useCallback for better performance

- Refactor Detail page to use ScrollableContainer
  - Remove manual scroll detection functions (checkApiScrollable, checkCardScrollable)
  - Remove scroll event handlers (handleApiScroll, handleCardScroll)
  - Remove scroll-related refs and state variables
  - Replace all card scroll containers with ScrollableContainer component
    * API info card
    * System announcements card
    * FAQ card
    * Uptime monitoring card (both single and multi-tab scenarios)

- Benefits:
  - Improved code reusability and maintainability
  - Reduced code duplication across components
  - Consistent scroll behavior throughout the application
  - Easier to maintain and extend scroll functionality

Breaking changes: None
Migration: Existing scroll behavior is preserved with no user-facing changes
