fix(06): set hasRrule on EventDetailPopover test fixtures

Plan 06-05 added hasRrule as a required field on the PWA CalendarOccurrence
type (mirroring 06-03's server-side field), but pre-existing fixtures in
EventDetailPopover.test.tsx did not set it — breaking tsc --noEmit / vite build
(vitest passed because esbuild strips types). Both fixtures are non-recurring
single events, so hasRrule: false is correct. Post-merge integration fix.
