Fix namespace conflicts in TankAlarm 112025 Arduino sketches

[Copilot]

Arduino compilation failed for all three TankAlarm-112025 sketches due to namespace conflicts between arduino::Stream and mbed::Stream on the Mbed OS platform.

Root Cause

The shared library used using namespace mbed;, which brought mbed::Stream into the global namespace. Third-party libraries (Notecard, ArduinoJson) expected arduino::Stream in the global namespace, causing ambiguity:

// Before - caused ambiguous Stream reference
#include <mbed.h>
using namespace mbed;  // Brings mbed::Stream into global
#include <Notecard.h>  // Expects arduino::Stream in global

Additionally, sketches redundantly included libraries already pulled in by the shared header, and the Client sketch redefined constants already declared in TankAlarm_Common.h.

Changes

TankAlarm-112025-Common/src/TankAlarm_Platform.h

• Replaced using namespace mbed; with specific type declarations
• Added using arduino::Stream; and using arduino::Print; for library compatibility

// After - explicit namespace resolution
#include <mbed.h>
using mbed::LittleFileSystem;
using mbed::BlockDevice;
using mbed::Watchdog;
using arduino::Stream;
using arduino::Print;

All three sketches

• Removed duplicate #include <Notecard.h> and #include <ArduinoJson.h>
• Removed conflicting NOTECARD_I2C_ADDRESS and NOTECARD_I2C_FREQUENCY constant definitions from Client sketch

All sketches now compile successfully for Arduino Opta.

Pull request overview

This PR resolves namespace conflicts that prevented compilation of TankAlarm-112025 Arduino sketches on the Mbed OS platform. The root cause was using namespace mbed; bringing mbed::Stream into the global namespace, which conflicted with arduino::Stream expected by third-party libraries.

• Replaced blanket using namespace mbed; with specific type declarations
• Added explicit using arduino::Stream; and using arduino::Print; for library compatibility
• Removed redundant include directives and constant definitions across all three sketches
