feat(discovery): add Apple parity fixes - infrastructure tracking, session recovery, default key guard
- Track infrastructure nodes (ROUTER, ROUTER_LATE, CLIENT_BASE roles) in DiscoveredNodeEntity and DiscoveryPresetResultEntity - Add markInterruptedSessions() DAO query for cold-start recovery - Add usesDefaultKey StateFlow to DiscoveryViewModel that checks primary channel PSK and disables scan when using default/cleartext key - Wire default key guard into ScanButton with accessibility description - Add discovery_start_scan_reason_default_key string resource - Update all test DAO fakes with KMP-compatible implementations Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
