fix(ui): apply blue PLANNED badge for finalized planning, drop dead converter statics

Bind the planning-parent badge to IsPlanActive/IsPlanFinalized so a
finalized plan shows the blue "planned" style instead of staying amber.
Remove the unused Instance statics on BoolToItalicConverter and
BoolToDraftOpacityConverter (registered via the App.axaml resource dictionary).
