Drafts are stored in localStorage and the sidebar badge was only refreshed from the composer's in-page save/remove events, so saving or deleting a draft in one tab left the count stale in every other open tab until a reload. Listen for the window storage event (fired in other tabs on localStorage writes) and refresh the badge when the drafts:available list changes or storage is cleared.

Problem
The drafts badge in the sidebar (and the bottom bar on mobile) goes stale across tabs. Save or delete a draft in one tab, and every other open tab keeps showing the old count until the page is reloaded.
Notifications don't have this problem because the server pushes `event:notifications.updateCount` over socket.io to every connected tab. Drafts, however, live entirely in `localStorage` on the client. `setupDrafts()` only refreshes the badge on page load and on the composer's `action:composer.drafts.save` / `action:composer.drafts.remove` jQuery events, which are per-tab.
Fix
Listen for the `storage` event on `window`. Browsers fire it in every other tab of the same origin whenever `localStorage` is written. The badge is refreshed when the `drafts:available` list (the key `drafts.getAvailableCount()` derives from) changes, or when storage is cleared (`key === null`).
Guests are unaffected: their drafts are in `sessionStorage`, which is per-tab and does not fire the event. The dropdown list itself needs no change since it is re-rendered on every `shown.bs.dropdown`.
