feat(10.1-02): run registered toolbar actions and scope plugin CSS per controller

- ListToolbar renders server-filtered actions after delete as outline buttons, busy during their POST
- ListView posts {} to toolbar/{action}, toasts, reloads the list and refetches the header partial
- Lists load controller assets too, so other controllers' stylesheet links are disabled on every open
- Vite dev server proxies {prefix}/assets to summer serve; dist rebuilt
