Version 1.2.0

Adds a new pause mode for ScrollBrake.

What’s new:
- Pause the extension from the popup
- Pause the extension from the full settings page
- Pausing now stops usage tracking indefinitely until you resume
- Resuming continues from your last saved state instead of resetting progress

Also included:
- UI updates to show when ScrollBrake is paused
- Internal improvements to keep lock timers and tracking state consistent when pausing and resuming
