Fix: Short packets panic over TCP

[sorokya]

This pull request improves error handling and reporting for short or invalid packets received over the network, and refines error messages when closing a player connection. The main changes are:

Error Handling and Reporting:

• In PacketBus, when a binary message is received that is too short (less than 4 bytes), the code now returns a detailed InvalidData error instead of silently returning None. This makes it easier to diagnose protocol issues.
• Similarly, when reading from the packet stream, if the buffer is too short (less than 3 bytes), a descriptive InvalidData error is returned, improving debugging and robustness.

Player Error Messaging:

• In run_player (in player_handle.rs), when an unknown error occurs, the error message logged when closing the connection now only includes the error itself, rather than a prefixed message. This results in clearer and more direct error reporting.
