Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to This change virtualizes the node list and changes how navigation and related TFT state are synchronized. The current version still risks lost telemetry, inconsistent battery display, unsafe map handling, and temporarily incorrect rotary/keypad navigation, so it is not merge-ready until these bounded correctness issues are addressed or explicitly accepted.

Restore air-quality and power telemetry handling.
Removing these overrides causes ViewController::packetReceived to dispatch air-quality and power telemetry to the empty MeshtasticView methods. NodeStore has no replacement mutation path. Incoming air-quality reports cannot update node-list IAQ highlighting, and power reports are discarded. Restore the overrides with model updates, or remove the dependent UI behavior consistently.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Use retained metrics and presence flags for the battery UI. The complete metrics overload merges partial fields into NodeStore, but the own-node battery UI still reads raw protobuf fields and gates refresh on metric values. An explicit zero battery or voltage update can therefore be skipped, while an omitted field can be treated as 0 instead of using the retained value, leaving the battery UI stale or inconsistent with the virtualized node rows. Read the merged metrics and refresh when has_battery_level || has_voltage is true.

The previous approach scaled UI objects and update work with the node database. This change keeps only the rows needed for the viewport and rebinds them while scrolling.
