  --[Added] Loading indicators and double-tap protection on all submit buttons across the app (login, register, OTP, KYC, add money, payments, profile, 2FA, and more) to prevent duplicate submissions and duplicate transactions
  --[Fixed] Biometric / fingerprint login was not working on Android and crashed on iOS (missing permissions and Face ID usage description) — now fully functional on both platforms
  --[Fixed] Reset password flow was not functional — passwords are now properly reset and failed attempts show the correct error instead of a false success
  --[Fixed] Account deletion request was sent with the wrong HTTP method and always failed — now works correctly (App Store compliance)

  --[Fixed] Android launcher icon: proper adaptive icon added (was missing entirely), correctly sized for all launcher shapes
  --[Improved] API error handling hardened across the app: request timeouts on file uploads, safe response parsing, user-friendly error messages instead of silent failures, and proper session handling on expired logins
  --[Improved] Defensive response parsing in payment, eSIM detail, and order detail models to tolerate backend data-type variations
  --[Improved] Upgraded 56+ packages to their latest compatible versions; removed discontinued and unused dependencies (smaller app size)
