New Params panel (Log viewer / Params / Metrics / Dashboards) declares a bare param via POST /api/params, mirroring Metrics' declare-then-list pattern including inline 400 error surfacing. Lifted the params list from LogPreview's own effect into App.tsx so declaring a param there updates the Columns picker immediately, without a page reload.
