Add comprehensive test coverage for the three AVM API upgrade endpoints:
- BatchValuationHandler: batch results, partial failures, error handling
- ValuationHistoryHandler: history retrieval, limit, empty state, errors
- ValuationComparisonHandler: multi-property compare, summary, edge cases
- AnalyticsController: route-level tests for all new endpoints
Fix async error handling in handlers by adding await to cache.getOrSet
calls so try/catch blocks properly catch rejections.
Fix pre-existing web test failures: add missing FLOOD_RISK_OPTIONS and
QUALITY_LABELS to valuation-form mock, update valuation-results assertions
to match current component rendering.
