feat(behandelportal): WP-64 werkvoorraad (queue) screen

New GET /werkvoorraad endpoint lists aanvragen still open (Ingediend/InBehandeling),
gated by the medewerker capability (CanBeoordelen) rather than the admin role — reuses
the existing ApplicationSummaryDto, no new DTO. GET /me now surfaces aanvraag:beoordelen
for a behandelaar so the FE can gate with the same AccessStore/capabilityGuard idiom
every other page uses.

FE: a behandeling domain type deliberately narrower than ssp's full AanvraagStatus
union (only the two open tags — illegal states unrepresentable), composed into a
werkvoorraad-list organism from existing shared/ui molecules. Replaces WP-61's
scaffold placeholder as the app's real landing page.
