chore: apply CodeRabbit quick fixes

[razinkele]

Apply a set of safe, mechanical fixes suggested by CodeRabbit:\n- Rename unused loop variables to start with underscore (_iteration, _idx)\n- Precompute column positions for DataGrid styling (avoid repeated list.index calls)\n- Rename unused lambda args in folium style_function to _x to satisfy ARG005\n\nThese are small style/performance fixes and should be safe to auto-merge once CI passes.

Follow-up: replaced mutable set with frozenset in �pp/config.py and narrowed a bare except in �pp/logger.py to OSError with a warning log (several CodeRabbit suggestions).
