refactor: Create reusable Tab components and update AssetsSidebarTab UI

- Add new Tab and TabList components with provide/inject pattern for
  state management
  - Replace TextButton-based tabs with new Tab components in
  AssetsSidebarTab
  - Update AssetSidebarTemplate to use semantic color tokens
  (bg-interface-panel-surface)
  - Improve tab styling with proper hover and focus states
