ENG-2907: Add Source filter to Request Manager

[nreyes-dev]

Ticket ENG-2907

Description Of Changes

Adds a Source multi-select filter to the Request Manager dashboard, exposing all PrivacyRequestSource enum values (Privacy Center, Request Manager, Consent Webhook, Fides.js, Dataset Test, Janus SDK). DSRs with a NULL source remain visible when no filter is applied.

The existing default exclusion guards for consent_webhook (toggle-gated) and dataset_test (always-on) are bypassed when an explicit source filter is set, so a user who selects those values in the dropdown gets them in the results instead of an empty list.

Code Changes

• Added source field and a single-to-list validator to PrivacyRequestFilter schema.
• Added source clause to filter_privacy_request_queryset; gated the consent_webhook and dataset_test exclusion guards on not filters.source so explicit filters win.
• Exposed source as a repeatable query param on the deprecated GET /privacy-request endpoint.
• Added SubjectRequestSourceMap / SubjectRequestSourceOptions constants and a Source multi-select to PrivacyRequestFiltersBar.
• Added source to FilterQueryParams, the nuqs URL state, and memoized params in usePrivacyRequestsFilters.
• Added source to the generated PrivacyRequestFilter TS type and updated PrivacyRequestFiltersBar test fixtures.
• Added schema tests for the source validator and endpoint tests covering single-source filtering, multi-source OR, null-source inclusion when unfiltered, and the consent_webhook / dataset_test override behaviors.

FE code looks good.

Nothing blocking, just 2 questions; seems like we could make the filter a lot simpler to reason about but it's not a show-stopper
