Bug: Enable/disable skills toggle resets to enabled state unexpectedly

## Description The enable/disable toggle for skills does not persist its state reliably. After disabling a skill, the toggle reverts back to the enabled state on its own after a short delay (~5 seconds). ## Steps to Reproduce 1. Open the Skills settings 2. Toggle a skill to: disabled -> enabled -> disabled 3. Wait ~ 5 seconds 4. Observe the toggle — it resets back to **enabled** without any user interaction ## Expected Behavior The toggle state (enabled/disabled) persists after being set. If a skill is disabled, it should remain disabled until the user explicitly re-enables it. ## Actual Behavior After setting a skill to disabled, the toggle reverts to enabled after ~5 seconds, suggesting the state change is not being saved or is being overwritten by a background sync/poll. https://github.com/user-attachments/assets/c1344865-cec9-46c1-ac77-497607105e61 ## Additional Notes - Delay before revert is approximately 5 seconds (may indicate a polling interval overwriting local state) - Intermittent — does not always reproduce, but occurs consistently enough to be noticeable --- _This issue was created by an AI agent (OpenHands) on behalf of the user._
