• error messages if sensor couldnt be initialized
• error messages if bluetooth couldnt be initialized
• small symbol if bluetooth connected
• box starts up regardless if sensors are not working

first merge #49 before this.

[Copilot]

🟡 Changes recommended

Header-level dependency coupling (notably Display.h including sensors and DistanceSensor.h including heavy ML headers) is likely to cause circular/expensive includes and should be restructured before approval.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

This PR improves startup resilience and user feedback by allowing the firmware to continue booting when individual sensors (or BLE) cannot be initialized, while surfacing clearer error/status information on the OLED.

Changes:

• Add bounded init retries plus “sensor missing” tracking (isPresent()) across sensors and BLE instead of blocking forever.
• Enhance OLED UI with a warning/error screen, a Bluetooth-connected icon, and a list of missing modules on the connection screen.
• Update PlatformIO platform/library versions and adjust DistanceSensor VL53L8CX integration to match updated headers/APIs.
