feat(services): F005 – complete service layer

New domain types:
- shortlist.ts: Shortlist, ShortlistItem, CreateShortlistInput
- review.ts: ReviewQueueItem, ReviewPriority, ReviewQueueStatus

New mock data:
- shortlists.ts: 2 sample shortlists
- reviewQueue.ts: 3 pending review items

New providers (interface + mockup):
- IShortlistProvider / MockupShortlistProvider (with 150ms latency)
- IReviewProvider / MockupReviewProvider (priority-sorted, with latency)
- IDashboardProvider / MockupDashboardProvider (computed from all mock data)

New services:
- reviewService: getQueue, approve, reject, assign
- shortlistService: CRUD + addItem/removeItem
- authService: wraps sessionStore, swappable for real auth
- dashboardService: getStats(organizationId?)

Enhancements:
- types.ts: typed ServiceErrorCode + ServiceError, Pagination alias
- aiService.ts: openRouterAIService stub (throws ai_generation_failed)
- lib/mockUtils.ts: mockDelay(ms) utility

New hooks:
- useUnifiedResults(needId?): joins matches+properties+signals → UnifiedMatchResult[]
- useReviewQueue: + useApproveReviewItem + useRejectReviewItem
- useMatchDetail, usePropertyDetail, useNeedProfiles aliases
