fix: clean service/client logs in uninstall scripts (#1846)

- Windows (x64/x86):
  - Remove delegation to `AmneziaVPN.exe -c`
  - Delete `%ProgramData%\AmneziaVPN\log\AmneziaVPN-service.log`
  - Delete current user logs at `%AppData%\AmneziaVPN.ORG\AmneziaVPN\log`
  - Remove empty parent dirs (app/org, log)

- Linux:
  - Delete only `/var/log/AmneziaVPN/AmneziaVPN-service.log` (preserve `post-uninstall.log`)
  - Delete current user logs at `$HOME/.local/share/AmneziaVPN.ORG/AmneziaVPN/log`
