fix(frontend, amber): source filter owners per resource kind and apply them to datasets

[tanishqgandhi1908]

What changes were proposed in this PR?

The Owner filter on the Datasets pages was broken on both sides:

1. Wrong list. <texera-filters> always read its Owner and ID dropdowns from WorkflowPersistService, so Datasets listed workflow owners and offered a workflow-ID filter.
2. No effect. VersionedResourceSearchQueryBuilder applied the date, id and full-text filters but dropped params.owners, so selecting an owner changed nothing.

Before:  Datasets -> filters -> workflowPersistService.retrieveOwners()  -> workflow owners
         owner=<email> -> VersionedResourceSearchQueryBuilder            -> ignored

After:   Datasets -> filters -> datasetService.retrieveOwners()          -> dataset owners
         owner=<email> -> VersionedResourceSearchQueryBuilder            -> USER.EMAIL predicate

Before -

After -

• filters.component.ts gains @Input() entityType, defaulting to Workflow, so the Workflows and
  unified search pages are untouched.
• VersionedResourceSearchQueryBuilder adds the getContainsFilter(params.owners, USER.EMAIL) the
  workflow builder already uses. The USER join was already in the FROM clause.
• The id dropdown hides where no id endpoint exists. Adding /dataset/user-dataset-ids and
  /model/user-model-ids is left to a follow-up feature.

Any related issues, documentation, discussions?

Closes #8059.

How was this PR tested?

Five new tests in filters.component.spec.ts (owners per kind, ids only for workflows, dropdown
hidden for datasets) and three in DatasetSearchQueryBuilderSpec (one owner renders the predicate,
several OR together but AND with the id filter, none renders nothing).

cd frontend && npx ng test $(grep -rl "FiltersComponent\|DatasetService" src/app | grep "spec.ts$" | sed 's/^/--include /' | tr '\n' ' ')
sbt 'testOnly *DatasetSearchQueryBuilderSpec'

909 frontend tests, 21 backend, all passing. Plus tsc --noEmit, eslint, prettier, scalafmtCheck.

Manual: signed in as a user with a shared dataset plus their own workflow, the Datasets page now
lists only the dataset's owner, ticking it narrows the list, and the id dropdown is gone. Workflows
page unchanged.
