### What changes were proposed in this PR?
Extends the existing Vitest spec for `OperatorMetadataService`
(`frontend/src/app/workspace/service/operator-metadata/operator-metadata.service.ts`,
codecov ~56%). The service fetches operator metadata once over HTTP (cached
via
`shareReplay`) and serves lookups from it; the existing spec only lightly
touched this. Adds 8 tests using `HttpClientTestingModule`, each flushing the
metadata GET with the `mockOperatorMetaData` fixture. No production code
changed.
- **`getOperatorMetadata`** — emits the fetched metadata to subscribers.
- **`getOperatorSchema`** — returns the matching `OperatorSchema` for a known
type; throws for an unknown type; throws "operator metadata is undefined"
before the request resolves.
- **`operatorTypeExists`** — `true` for a fetched type, `false` for an
unknown
one and before the request resolves; matches the user-friendly name only
when
that filter is enabled; honors case-insensitive matching when requested.
### Any related issues, documentation, discussions?
Closes #6592
### How was this PR tested?
Extended unit tests, run locally in `frontend/` (all green; the failure path
was
verified by breaking an assertion to confirm the suite goes red):
```
ng test --watch=false --include
src/app/workspace/service/operator-metadata/operator-metadata.service.spec.ts
# Tests 11 passed (11) (3 existing + 8 new)
eslint <spec> # clean
prettier --check # clean
```
