refactor: centralize platform-specific behavior in platform services

- Add platform-specific capability methods to PlatformService interface:
  - getExportInstructions()
  - getExportSuccessMessage()
  - needsSecondaryDownloadLink()
  - needsDownloadCleanup()

- Update platform service implementations:
  - WebPlatformService: Implement web-specific export behavior
  - CapacitorPlatformService: Implement mobile-specific export behavior
  - ElectronPlatformService: Add placeholder for export functionality
  - PyWebViewPlatformService: Add placeholder for export functionality

- Refactor DataExportSection component:
  - Remove direct platform checks (isWeb, isCapacitor, etc.)
  - Use platform service capabilities for UI behavior
  - Improve error handling and logging
  - Add proper cleanup for web platform downloads

- Update PlatformServiceFactory:
  - Make getInstance() async to support dynamic imports
  - Improve platform service initialization

- Fix code style and documentation:
  - Update JSDoc comments
  - Fix string quotes consistency
  - Add proper error handling
  - Improve logging messages

- Update Vite config:
  - Add all Capacitor dependencies to external list
  - Ensure consistent handling across platforms
