Session does not time out on Inputs page

[coffee-squirrel]

Expected Behavior

Session expiration should occur regardless of which page a user is viewing.

Current Behavior

When viewing the Inputs page (/system/inputs), at minimum the /api/cluster/inputstates request (https://github.com/Graylog2/graylog2-server/blob/5.2.3/graylog2-web-interface/src/stores/inputs/InputStatesStore.js#L42) gets sent without request header X-Graylog-No-Session-Extension: true, which results in the session never expiring.

Steps to Reproduce (for bugs)

1. Have a Graylog 5.2.3 5.2.5 environment
2. Open your browser's dev tools network tab
3. Navigate to the Inputs (/system/inputs) page
4. Note the aforementioned requests are sent without the request header X-Graylog-No-Session-Extension: true

Context

I happened to leave the Inputs page up, and noticed I was still logged in the next day.

Similar to #10613 and #18063.
