PropValue::ParamRow/ParamAddRow, the PropParamInput/Commit/Delete/AddNew messages, their command_driver handlers (on_prop_param_commit/_delete/ _add_new, resolve_named_parameter_edit), and their render functions all already existed — but nothing ever constructed the "Parameters" section that would route data to them, so the whole inline add/rename/redefine/ delete workflow was unreachable from the UI. Adds that missing section to the no-selection page in refresh_properties, alongside a new PropValue::ParamsVisibilityToggle header row (mirrors the existing show_constraint_values setting) for toggling whether constraint pills show their driven value/parameter name. Users can now manage named parameters inline in the Properties panel (live resolved values, add/rename/redefine/delete) as an alternative to the separate PARAMETERS modal, which continues to work unchanged.
