chore(deps): upgrade frontend to Angular 17

[aglinxinyuan]

Summary

This PR upgrades the frontend/ app from Angular 16 to Angular 17 and updates the related toolchain so the app still builds and tests successfully.

What Changed

• Upgraded Angular core packages to 17.3.x
• Upgraded Angular CLI/devkit/compiler tooling to 17.3.x
• Upgraded Angular-adjacent packages that needed to move with the framework:
  • @angular/cdk
  • ng-zorro-antd
  • ngx-markdown
  • zone.js
  • typescript
  • @angular-builders/custom-webpack
  • Angular ESLint packages
• Added explicit devkit/schematics/webpack dependencies needed by the current workspace setup
• Regenerated frontend/yarn.lock

Code Adjustments

• Updated markdown rendering to handle the newer ngx-markdown parse API, which can return asynchronously
• Fixed a duplicate computed-property assignment that TypeScript 5.4 rejects
• Removed an invalid CSS declaration that Angular 17’s stylesheet pipeline surfaced
• Cleaned a few template/CSS warnings exposed by the newer compiler/toolchain:
  • unnecessary optional chaining in the dataset detail template
  • start alignment values changed to flex-start where appropriate

Any related issues, documentation, discussions?

Closes #4402

How was this PR tested?

• yarn.cmd install
• yarn.cmd build
• yarn.cmd test --watch=false

Build and tests both pass.

Tested the frontend manually, including dataset uploading, workflow editor, and UDF editor.
