Shayan/FEQ-2696/Fix redundant Cloudflare trace API calls

[shayan-deriv]

Problem

Multiple simultaneous requests to cloudflare.com/cdn-cgi/trace during app initialization causing console errors and unnecessary network calls.

Solution

Implemented Promise caching in getCountry utility to deduplicate requests:

• Caches ongoing Promise to prevent parallel calls
• Clears cache after completion
• Maintains existing cookie fallback
