Initial commit: @b2c/first_page HarmonyOS stage-mode HAR

## Repository - HarmonyOS stage-mode HAR module, consumed by host app - No standalone build — hvigorw, oh_modules, and ../biz_quote absent here ## Architecture ### Feed Cards - FirstPage.createNodeView dispatches cards by FirstPageConstant.KEY_* - Card config from first_page_cards_config.json loaded by FirstPageCardsConfigLoader - Public entrypoint: Index.ets ### Market Ranking (src/main/ets/market-ranking/) - HTTP: MarketRankingDataFetcher fetches recommend_futures contracts - HQ: MarketRankingHqRequestClient subscribes via 4106/frame 2201/scenario qht_qihuo_sort - TCP reconnect rebuilds subscription from original HTTP contract list - Async callbacks guarded by request/subscription versions ### Other Cards - HotList, CommodityOptions, AiDiagnosis, AiRiseFall, SelfSelectedStock, CustomEntryList, FourEntryList - Each has DataFetcher + HQ request client + NodeComponent ## Key Changes (from CardHarmonyOS reference) - Added MetricId, PeriodId, SortOrder enums (MarketRankingModels.ets) - Replaced string comparisons with enum switches in thirdColumnTitle/Value/Color - Removed redundant undefined guards in thirdColumnColor/priceColor, delegated to riseFallColor - Inlined priceColor(), use riseFallColor directly - Tab bar Stack.height(30), Alignment.End (reverted from 46/TopEnd) - Name column fontWeight removed (default regular)
