feat: Update login page theme colors and add i18n support

- Changed login page gradient from blue to match dark theme colors
- Updated ripple effects to use theme primary color
- Added i18n translation keys for login page (auth.tagline, auth.description, auth.welcomeBack, auth.createAccount, auth.continueExternal)
- Updated all language files (en, zh, de, ru, pt-BR) with new translations
- Fixed TypeScript compilation issues by clearing build cache
