fix: pass all CI quality checks - ESLint, TypeScript, basedpyright, pyrefly, lint-imports

Frontend:
- Migrate deprecated imports: modal→dialog, toast→ui/toast, tooltip→tooltip-plus,
  portal-to-follow-elem→portal-to-follow-elem-plus, select→ui/select, confirm→alert-dialog
- Replace next/* with @/next/* wrapper modules
- Convert TypeScript enums to const objects (erasable-syntax-only)
- Replace all `any` types with `unknown` or specific types in workflow types
- Fix unused vars, react-hooks-extra, react-refresh/only-export-components
- Extract InteractionMode to separate module, tool-block commands to commands.ts

Backend:
- Fix pyrefly errors: type narrowing, null guards, getattr patterns
- Remove unused TYPE_CHECKING imports in LLM node
- Add ignore_imports entries to .importlinter for dify_graph boundary violations
