Add API client layer and user endpoint contracts

[mintlify]

Summary

Updates repositories/d-sports-engage-native.mdx to document the native app's API client architecture and user endpoint contracts, triggered by d-sports-engage-native@7902420.

Trigger repo changes

• lib/api/client.ts — typed HTTP client with strict normalized envelope parsing
• lib/api/user-api.ts — user follow/unfollow request shapes and top-users response typing aligned to backend contracts
• lib/api/index.ts — useApi() hook exposing all API domain modules

Doc changes

• repositories/d-sports-engage-native.mdx — added three new sections:
  • API client layer — overview of the lib/api/ client and Clerk auth integration
  • Normalized envelope contract — documents the strict { success, data?, error?, code? } response shape
  • API modules — table of all domain modules with useApi() usage example
  • User API endpoints — full endpoint table with note on follow/unfollow request shapes and top-users response typing
