main: Handle toggle-dnd-request and auto-revert DND in ipcMain.

When a duration is provided, sets a timer to automatically revert DND mode. Ensures only one timer is active at a time, and cleans up appropriately when DND is turned off early. We import dnd-util.js to handle the DNDUtil.toggle() in our timer logic.
Fixes #561.
