dash: use currentIndex for width, restore binding (#1286)

* [CI] chore: update flake

* Dashboard perf settings save, visibility on none enabled

* Dashboard heigh stutter fixed, persist current tab

* restore binding

* wrapper async=false

* ScriptModel, centralized tabs/panes, individual toggle

* fixes, missed mediaUpdateInterval, passing values

* add binding back, ensure active tab uses bar.currentIndex
