Add 1-hour cache timeout and fix pull-to-refresh across iOS

- Add configurable cache timeout (CACHE_TIMEOUT_MS) to DataManager
- Fix cache to work with empty results (contractors, documents, residences)
- Change Documents/Warranties view to use client-side filtering for cache efficiency
- Add pull-to-refresh support for empty state views in ListAsyncContentView
- Fix ContractorsListView to pass forceRefresh parameter correctly
- Fix TaskViewModel loading spinner not stopping after refresh completes
- Remove duplicate cache checks in iOS ViewModels, delegate to Kotlin APILayer
