Fix: TORCH dashboard missing active locks created before midnight

The TORCH dashboard was filtering events using `since: <today 00:00 UTC>`, which excluded active locks created on the previous day (e.g., late-night daily locks or weekly locks).

This change updates the `since` filter to look back 7 days, ensuring that all potentially active locks (including weekly cadence) are retrieved and displayed.

Steps:
1.  Modified `views/dev/agent-dashboard.html` to set `since` to `Date.now() - 7 days`.
2.  Verified the fix by creating a reproduction script `reproduce_issue.py` (which confirmed the issue) and a verification script `verify_dashboard.py` (which confirmed the fix).
3.  Verified the visual output with `verification.png`.
