Callbacks and Activity tabs fixed: no more endless loading

If you opened the 🔁 Callbacks or 🔔 Activity tab in your dashboard recently and stared at a “Loading…” spinner that never finished — that was a real bug, and it’s fixed.

What you’ll notice

• Your callback queue always loads. Every callback request your customers leave on your call pages shows up, pending requests first (the ones waiting longest at the top), each with 📞 Call Back Now, ✓ Mark Complete, and Dismiss. The pending count badge on the tab stays accurate.
• Your activity feed always loads. Every call, page view, callback request and completion across your pages — with type and channel filters, a live refresh every 30 seconds, and the 🔔 bell badge telling you how many new events arrived.
• No more dead spinners. If your connection drops or your session expires, the tab now says so plainly and offers a ↻ Retry button — instead of spinning forever.
• Helpful empty states. No callbacks yet? The tab tells you customers can request one from any call page, instead of showing a blank box.

Why it happened

Two gaps combined: the dashboard waited on the network with no time limit, and certain failures (like an expired login session) were silently swallowed — so nothing ever replaced the spinner. Every tab load is now bounded by a 15-second timeout, and every failure path renders an actionable state.

This was verified with 19 new automated unit tests and 15 end-to-end browser checks against the real dashboard code — including the mobile layout at 375px — all green.

Nothing you need to do: the fix is live in your dashboard now. Open the Callbacks tab and your queue is there.
