v1.5.2 — Field Link Peer Sync + MGRS Fix

What's New

Field Link is now fully operational. Teammates appear on the map and peer list in real time over Bluetooth.

Bug Fixes

• BLE peer sync: Fixed write mode so the GATT server receives data from connected peers
• MGRS accuracy: Corrected 100km grid square letter calculation affecting most UTM zones
• Position deserialization: Fixed timestamp injection so position payloads decode correctly
• Map controller crash: Deferred map centering to post-frame callback

New Features

• Mode-specific callouts: Tactical quick-send labels change per operational mode
• Peer callsigns: Display names shown on map markers and peer list
• PIN prompt on scan join: Prompts for PIN with a Skip option for open sessions

UI Improvements

• SOS button repositioned above zoom controls
• Annotation toggle moved above callout bar
• PIN keyboard rewritten (no flicker)
• Role and callsign changes refresh peer list immediately
