Query tab does not send request and __CATEGORIES__ fails after page reload until switching tabs

[N0LOD1N]

• [x] I am on the latest ActivityWatch version.
• [x] I have searched the issues of this repo and believe that this is not a duplicate.

• OS name and version: Microsoft Windows 11 Pro, Version 10.0.22631 Build 22631
• ActivityWatch version: v0.13.2

Describe the bug

When the page is refreshed and the Query tab is opened first, running a query that uses CATEGORIES fails with: Categories was used in query, but no categories have been defined yet. No /api/0/query request is sent in Network tab. The issue disappears if I switch to another tab (e.g., Reports) and back to Query — then queries run normally.

To Reproduce

1. Open ActivityWatch Web UI in browser, Query page.
2. Press F12 → go to Network → enable Preserve log.
3. Refresh the page (F5).
4. Click Run on a query using CATEGORIES.
5. Observe that:

• No /api/0/query request is sent.
• Error message appears: Categories was used in query, but no categories have been defined yet.

Workaround: Switch to another tab (Reports or Settings), then back to Query. After that, queries run normally and /api/0/query requests are sent.

Expected behavior

Queries in Query tab should work immediately after page reload without needing to switch tabs first.
