refactor: apply style guide compliance across auth, dashboard, and tool pages

- Replace hardcoded color classes with design system tokens (error, success, warning, info)
- Replace raw HTML inputs with Input component from @tpmjs/ui
- Replace raw HTML buttons with Button component
- Add eye/eyeOff icons for password visibility toggle
- Add mail icon for verify-email page
- Fix text colors to use semantic tokens (text-error, text-success, text-warning)
- Fix background colors to use opacity tokens (bg-error/10, bg-success/10)
- All pages now properly support dark mode through CSS custom properties
