bug: useRealtimeRunsWithTag hides runs older than 24h even with createdAt: '1w' #3018

Describe the bug

Runs that have been running for 24+ hours (or created more than 24 hours ago) do not appear in useRealtimeRunsWithTag on the client, even when passing createdAt: '1w'. They are visible via runs.list and in the dashboard.

Expected: With createdAt: '1w', all runs with the given tag from the last week (including long-running ones) are streamed and appear in the hook.

Actual: The realtime endpoint caps the createdAt filter to REALTIME_MAXIMUM_CREATED_AT_FILTER_AGE_IN_MS (default 24h). So only runs created in the last 24 hours are included; runs older than that are excluded regardless of the client's createdAt value.

Reproduction repo

To reproduce

1. Create a run with a tag and let it run (or sit in a waiting state) for 24+ hours.
2. In the app, use useRealtimeRunsWithTag('your-tag', { createdAt: '1w' }).
3. The run does not appear in the hook's runs array, but it does appear in runs.list and in the dashboard.

Additional information

• Root cause: apps/webapp/app/services/realtimeClient.server.ts → #calculateCreatedAtFilter clamps the filter to env.REALTIME_MAXIMUM_CREATED_AT_FILTER_AGE_IN_MS (default 24h in env.server.ts).
• No client-side workaround; the cap is applied server-side.
• Fix: increase the default (or make it configurable), or allow the client's requested window up to a defined max.
