refactor(mobile): Remove i18n, expand core screens, update plan

BREAKING: Removed multi-language support (i18n) - will be re-added later

Changes:
- Removed i18n system (6 language files, LanguageContext)
- Expanded WalletScreen, SettingsScreen, SwapScreen with more features
- Added KurdistanSun component, HEZ/PEZ token icons
- Added EditProfileScreen, WalletSetupScreen
- Added button e2e tests (Profile, Settings, Wallet)
- Updated plan: honest assessment - 42 nav buttons with mock data
- Fixed terminology: Polkadot→Pezkuwi, Substrate→Bizinikiwi

Reality check: UI complete with mock data, converting to production one-by-one
