feat: Improve onboarding wizard UI, UX and dark mode support

This commit implements multiple improvements to the onboarding wizard:

**1. Unified UI Components:**
- Created InfoCard component for consistent "why is important" blocks across all steps
- Created TemplateCard component for consistent template displays
- Both components use global CSS variables for proper dark mode support

**2. Initial Stock Entry Step Improvements:**
- Fixed title/subtitle positioning using unified InfoCard component
- Fixed missing count bug in warning message (now uses {{count}} interpolation)
- Fixed dark mode colors using CSS variables (--color-success, --color-info, etc.)
- Changed next button title from "completar configuración" to "Continuar →"
- Implemented stock creation API call using useAddStock hook
- Products with stock now properly save to backend on step completion

**3. Dark Mode Fixes:**
- Fixed QualitySetupStep: Enhanced button selection visibility with rings and shadows
- Fixed TeamSetupStep: Enhanced role selection visibility with rings and shadows
- Fixed AddressAutocomplete: Replaced all hardcoded colors with CSS variables
- All dropdown results, icons, and hover states now properly adapt to dark mode

**4. Streamlined Wizard Flow:**
- Removed POI Detection step from wizard (step previously added complexity)
- POI detection now runs automatically in background after tenant registration
- Non-blocking approach ensures users aren't delayed by POI detection
- Removed Revision step (setup-review) as it adds no user value
- Completion step is now the final step before dashboard

**5. Backend Updates:**
- Updated onboarding_progress.py to remove poi-detection from ONBOARDING_STEPS
- Updated onboarding_progress.py to remove setup-review from ONBOARDING_STEPS
- Updated step dependencies to reflect streamlined flow
- POI detection documented as automatic background process

All changes maintain backward compatibility and use proper TypeScript types.
