Update create twenty app scaffolded front component (#20733)

- Replace inline SVG icons with proper Avatar and icon components
(IconBox, IconHierarchy, IconLayout, IconSettingsAutomation) from
twenty-sdk/ui in the scaffolded front component
  template
- Strip trailing slashes from workspace/API URLs in both
create-twenty-app CLI and twenty-sdk remote commands to prevent
malformed requests
  - Fix the application settings link to navigate to #installed anchor
- Bump twenty-sdk, twenty-client-sdk, and create-twenty-app versions to
2.6.0
