fix windows conda run encoding in workflows

Enable UTF-8 for later conda run commands so anaconda-client version output does not fail under the Windows code page.

fix conda plugin timing in windows workflows

Set CONDA_NO_PLUGINS only after mamba installs anaconda-client so setup-miniconda can initialize normally while later conda commands avoid the anaconda-auth plugin crash.

fix conda plugin crash in windows workflows

Disable conda plugins in build jobs so anaconda-auth from anaconda-client does not break conda info or conda run on Windows.

fix windows mamba bat quoting in workflows

Pass the mamba.bat command to cmd without nested escaped quotes so Git Bash does not produce an invalid program name.
