Enhance capture cancellation handling and logging in CaptureListener

[Adammatthiesen]

This pull request improves the handling and logging of canceled Pokémon capture events during battles in the CaptureListener class. The main changes add detailed logging, ensure proper cleanup when a capture is canceled mid-battle, and send the correct network packet to notify the client.

Key improvements to capture cancellation during battles:

• Added detailed info logs for each step of the capture cancellation process, including reasons for cancellation and error handling.
• When a capture is canceled during a battle, the code now:
  • Checks for a valid battle instance and capture action, logging and returning early if not found.
  • Sends a BattleCaptureEndPacket to notify the client that the capture has ended. [1] [2]
  • Calls finishCaptureAction to properly clean up the capture action in the battle.

These changes make the capture cancellation process more robust and transparent, especially in the context of ongoing battles.
