Technical summary

patronictl show_diff can pass ydiff options in a shape that markup_to_pager does not understand.

Normalize the ydiff opts/theme arguments before calling markup_to_pager from ctl.py show_diff.

This issue is about the ydiff pager integration, so the patch should preserve diff generation and only fix option passing.

The snippet uses native project logic; the raw diff string is rendered before Patroni sends it to the pager. The helper result is consumed directly by the patched code path.

After applying the patch, keep the import smoke test for the affected package:

python3 -c "import patroni; print('smoke test OK')"
