feat(frontend): add the Models page

[tanishqgandhi1908]

What changes were proposed in this PR?

Adds the Models page: list, search, create, rename, delete.

To get there without adding a third type === "..." arm everywhere, each resource kind now supplies a descriptor — icon, routes, ownership, rename, description, filter sources — aggregated by ResourceRegistryService. card-item, list-item and filters read that instead of branching on the entry type. Workflow, dataset, project and file behave exactly as before; models are just one more descriptor.

The page lists from /model/list and filters client-side, so models stay out of global search until the hub backend lands. That endpoint is now scoped to what the caller was granted: ResourceAccess.listVisible takes an includePublic flag, defaulted so /dataset/list — whose picker legitimately offers public datasets to read as workflow input — is unchanged. Your Work → Models therefore shows your own and shared models only, exactly like Your Work → Datasets.

The sidebar and cards use Material Symbols hub (Apache-2.0, attributed in LICENSE), registered once through NzIconService. ng-zorro has no icon that reads as an ML model, and the denser Material glyphs are illegible at the sidebar's 15px.

Any related issues, documentation, discussions?

Groundwork for #6499; does not close it.

models_enabled ships false until the detail page lands. /user/model/:mid has no component yet, so the model descriptor deliberately carries no privateRoute — a model card does not navigate, rather than hitting the ** wildcard and landing on Workflows — and creating a model refreshes the list instead. The flag is toggleable live in Admin → Settings, and hides the sidebar entry, not the route, same as datasets_enabled.

How was this PR tested?

56 new tests across the registry, ModelService, the Models page and the create modal.

cd frontend && npx ng test \
  --include src/app/dashboard/service/user/resource-registry/resource-registry.service.spec.ts \
  --include src/app/dashboard/service/user/model/model.service.spec.ts \
  --include src/app/dashboard/component/user/user-model/user-model.component.spec.ts \
  --include src/app/dashboard/component/user/user-model/user-model-creator/user-model-creator.component.spec.ts

sbt 'testOnly *ModelResourceSpec'

Regression: 417 frontend tests across 15 spec files covering card/list items, filters, search and the sidebar, and 23 in ModelResourceSpec. Plus tsc --noEmit, eslint, prettier and scalafmtCheck.

Four spec edits. Three are fixture or tab-count updates. The fourth is a behavior change stated on purpose: "listModels should include public models owned by another user" is inverted to omit, since that assertion described the bug above; it now also checks the model is still reachable through getPublicModel, so public discovery stays covered.

Manual: Admin → Settings → Models on, create a model, search it by framework, switch card/list views, rename inline, delete.
