Pull Request Overview

This PR fixes blocking HTTP calls by implementing asynchronous telemetry sending on the RP2040 platform. The key changes focus on moving HTTP POST operations to a separate core to prevent blocking the main application loop.

• Introduces a lock-free SPSC queue for telemetry data on RP2040 with core-1 worker thread
• Refactors configuration from separate host/port to unified base URL
• Maintains synchronous behavior on ESP8266/ESP32 platforms for compatibility
