Collapse the five scanner status models into two shared shapes, ActiveScannerStatus and PassiveScannerStatus, mirroring the backend's active/passive vocabulary. Replace the five near-identical per-scanner detail card files with a single scanner_status_cards.dart (two shared resolvers plus a config list), and rebuild the combined home card to iterate a list of scanners with two shape resolvers instead of five copy-pasted resolve methods. Extract two reusable mixins: - PeriodicRebuild: the shared once-a-second "rebuild to refresh elapsed text" timer used by the scanner cards and the stale indicator. - PaginatedListState: the shared pagination state, page-size/page-count getters, cancel-token-aware fetch orchestration, and disposal used by the device and notification lists. No behaviour change; ~900 lines removed. Tests and analyzer pass.
