Add request deduplication mechanism to prevent duplicate GET requests
to the same endpoint within the same timeframe, significantly reducing
unnecessary network overhead.

**Changes:**
- Add `patchAPIInstance()` function to intercept and deduplicate GET requests
- Implement in-flight request tracking using Map with URL+params as unique keys
- Apply deduplication patch to both initial API instance and `updateAPI()` recreated instances
- Add `disableDuplicate: true` config option to bypass deduplication when needed

**Benefits:**
- Eliminates redundant API calls caused by component re-renders or rapid user interactions
- Reduces server load and improves application performance
- Provides automatic protection against accidental duplicate requests
- Maintains backward compatibility with existing code

**Technical Details:**
- Uses Promise sharing for identical concurrent requests
- Automatically cleans up completed requests from tracking map
- Preserves original axios functionality with minimal overhead
- Zero breaking changes to existing API usage

Addresses the issue observed in EditChannel.js where multiple calls
were made to the same endpoints during component lifecycle.
