Dev/andres/v4.0 rdp logs

[aschumann-virtualcable]

This pull request primarily removes excessive or redundant debug and info logging from the RDP transport scripts for Linux and macOS, making the code cleaner and reducing unnecessary log output. At the same time, it improves the usefulness of remaining logs by adding targeted debug/error messages for executable discovery and error cases.

Logging cleanup and improvements:

• Removed unnecessary debug and info logging statements from RDP file preparation and client execution in direct.py and tunnel.py for both Linux and macOS, reducing log noise and focusing logs on relevant events. [1] [2] [3] [4] [5] [6] [7] [8] [9]

• Added targeted debug and error logging for the discovery and selection of RDP clients (Thincast, UDSRDP, XFREERDP) on Linux and macOS, making it easier to diagnose client selection issues. [1] [2]

Code comments and documentation:

• Updated a Spanish comment to English for clarity in direct.py.

Signature updates:

• Updated .signature files to reflect changes in the corresponding Python scripts. [1] [2] [3] [4]
