Context: Explore Data Service Performance Optimization

Goal: Reduce background CPU and battery usage by pausing ExploreDataService updates when the tab is hidden.

Scope:

• js/services/exploreDataService.js

Problem:

• The service runs two setInterval timers (1 minute and 5 minutes) to refresh watch history counts and tag IDF.
• These run even when the tab is hidden or minimized, consuming resources unnecessarily.

Proposed Solution:

• Modify the interval callbacks to check document.hidden. If true, skip the update.
• Add a visibilitychange listener to trigger an immediate update when the tab becomes visible (if the data is stale).

Assumptions:

• document.hidden is supported in target browsers (modern browsers support it).
• Users do not need real-time updates for "explore" data when the tab is not visible.
