Improve desktop script runs with timestamps & logs

Improve script execution in the desktop app by introducing timestamped
filenames and detailed logging. These changes aim to facilitate easier
debugging, auditing and overall better user experience.

Key changes:

- Add timestamps in filenames for temporary files to aid in
  troubleshooting and auditing.
- Add application logging throughout the script execution process to
  enhance troubleshooting capabilities.

Other supporting changes:

- Refactor `TemporaryFileCodeRunner` with subfunctions for improved
  readability, maintenance, reusability and extensibility.
- Refactor unit tests for `TemporaryFileCodeRunner` for improved
  granularity and simplicity.
- Create centralized definition of supported operating systems by
  privacy.sexy to ensure robust and consistent test case creation.
- Simplify the `runCode` method by removing the file extension
  parameter; now handled internally by `FileNameGenerator`.
