refactor(arch): eliminate direct service calls in components — route all through hooks

New hook files:
- useAuth.ts: useLogin, useSwitchDemoRole, useSwitchOrganization
- useAI.ts: useParseNeed, useGenerateOfferEmail, useGenerateDecisionBrief, useParseListingText
- useAssistant.ts: useAssistantSuggestions (useQuery), useAssistantAnswer (useMutation)
- useOfferReport.ts: useOfferReportByInquiry, useCreateOfferReport, useUpdateOfferReport, useGenerateOfferReportPdf
- useInquiryReport.ts: useInquiryReportByInquiry, useCreateInquiryReport, useUpdateInquiryReport, useFinalizeInquiryReport
- useMarketReport.ts: useMarketReport
- useWeighting.ts: useDefaultWeights (synchronous wrapper)
- useUnitMatches.ts: useUnitMatchesMap, useUnitBundle, useBundleMatches (useMemo wrappers)

Extended hooks: useProperties (add update/create/remove mutations),
useNeeds (add useCreateNeed), useMatches (add useNeedMatchesForProperty,
useAdditionalMatchesForInquiry), useReviewQueue (add useCreateReviewTask)

Updated 21 components/pages: all direct service imports replaced with hooks.
Deliberate exception: getRecommendedActions in DataQuality.tsx (pure sync utility, no provider access).
