feat: Device notification mute/unmute (upstream #822)

[Starosdev]

Summary

Port feature from upstream AnalogJ/scrutiny PR AnalogJ#822 to allow muting notifications per device.

Problem

When a drive is degraded and waiting for replacement, users receive repeated failure notifications. There's no way to silence notifications for a specific device while still monitoring others.

Solution

Add a muted field to devices and UI controls to enable/disable notifications per device.
