refactor(frontend): convert all components to standalone (#4873)

### What changes were proposed in this PR?

Run Angular's official `ng generate @angular/core:standalone
--mode=convert-to-standalone --defaults` across the frontend. Flips
every `@Component({ standalone: false })` to `standalone: true`,
auto-derives per-component `imports: [...]` from each template's
directive usage, and updates `AppModule.declarations` accordingly.

Plus one manual fixup: 5 components (admin-user, filters, user-dataset,
user-workflow, menu) reference `<nz-button-group>` / `[nzBorderless]`
which ng-zorro-antd v21 has removed. The legacy builder didn't catch
these latent dead-code refs; the new strict builder does. Add `schemas:
[CUSTOM_ELEMENTS_SCHEMA]` to keep this PR focused — replacing with
`<nz-space-compact>` belongs in its own follow-up.

### Any related issues, documentation, discussions?

Closes #4864.

After this and #4862 land, the 43 component specs + 13 service specs
currently excluded for the NgModule-scope template-check failure can
come off the exclusion list in a follow-up.

### How was this PR tested?

`yarn run build` exits 0 with a clean prod bundle. Given the lack of
test suites in frontend, I manually tests this locally.
Tested login, create dataset, file upload, create workflow, run
workflow, etc.
