fix(posts): keep CI Fiber material codes case-insensitive after reload

System.Text.Json rebuilds MaterialCodes with the default ordinal comparer, so a saved config matched 'Mild Steel' but not 'mild steel' and silently fell back to the default code. The setter now re-keys assigned maps case-insensitively.
