fix: resolve port conflict (mana-image-gen 3025→3026) and replace APP_URLS with internal routes

- mana-image-gen: change default port from 3025 to 3026 to avoid conflict with mana-llm
- Dashboard widgets (12): replace APP_URLS.{app}.dev/prod with internal route paths (/todo, /calendar, etc.)
  and remove target="_blank" since all apps are now internal routes in the unified app
- Home page: use goto() for internal apps, keep window.open() only for external apps (matrix, arcade)
- AppRow: remove unused APP_URLS import
