Take the support drawer back out of the topbar (sow-nodebb-plugin-support#10)

Support case notifications now live in the notification bell, as a "Cases"
filter button added by nodebb-plugin-support on core's own hooks. The plugin
owns all of it, so this theme's second bell — its icon, drawer, client code,
language keys and tests — comes out.

The theme was the wrong home for it. The drawer's markup and JS lived here, so
whether the support plugin could notify anyone depended on which theme a forum
ran. Nothing about support belongs in a theme.

The `/support` link is unaffected; it comes from the ACP navigation, which
this theme already renders in both the desktop bar and the mobile drawer.

Checked in a browser on the dev stack: no support icon in the topbar, and the
bell's new tab filters a mixed notification list correctly.
