Mirrors the existing unread-drawer pattern: a new dropdown next to the
notification bell, gated on templateData.support.visible (injected by
the support plugin's filter:middleware.renderHeader hook, on every page
render, for viewers with any support access at all). Opening it fetches
GET /plugins/support/notifications via the api module, renders up to
10 entries by textContent (never innerHTML), and marks everything read
via POST .../notifications/read, clearing the badge client-side.
Also present in the mobile burger drawer, same gating.
ponytail: no live socket push for this badge (core's own unread/notification
counts get one); it only catches up on the next full page load after the
box is opened. Noted in client.js as the upgrade path if that gap matters.
Verified live against sow-nodebb-plugin-support's dev NodeBB stack (theme +
plugin both mounted): icon hidden for a user with no support access, badge
count and dropdown contents correct for a reviewer, badge clears on open.
Full plain-node test suite passes.
