/**
 * Covers the Reset action on a GitHub review watch. The flow:
 *   1. Watch creates a task for a mock PR (via trigger).
 *   2. User clicks Reset on the settings page → confirmation dialog shows
 *      the preview count ("delete N task(s)").
 *   3. Confirm → backend cascade-deletes the task, wipes dedup, and queues
 *      the same PR for re-import.
 *
 * Store-level reset coverage for the shared `watchreset.Run` flow lives in
 * Go unit tests.
