Fix Arduino CI workflow to include TankAlarm-112025-Common library

[Copilot]

Commit 311de37 introduced TankAlarm-112025-Common as a shared library and refactored all three sketches to use it, but didn't update the CI workflow. Compilation fails because Arduino CLI can't find the library headers.

Changes:

• Added --library TankAlarm-112025-Common flag to all three compile commands in .github/workflows/arduino-ci-112025.yml
• Added TankAlarm-112025-Common/** to workflow trigger paths

# Before
arduino-cli compile --fqbn arduino:mbed_opta:opta \
  TankAlarm-112025-Client-BluesOpta/TankAlarm-112025-Client-BluesOpta.ino

# After  
arduino-cli compile --fqbn arduino:mbed_opta:opta \
  --library TankAlarm-112025-Common \
  TankAlarm-112025-Client-BluesOpta/TankAlarm-112025-Client-BluesOpta.ino

Pull request overview

This PR fixes the Arduino CI workflow compilation failures introduced in commit 311de37 by adding the required TankAlarm-112025-Common library reference. The workflow was failing because Arduino CLI couldn't locate the shared library headers that all three sketches depend on.

Key changes:

• Added --library TankAlarm-112025-Common flag to all three Arduino CLI compile commands
• Added TankAlarm-112025-Common/** to workflow trigger paths for both push and pull_request events
