1. Fix monthly/annual toggle:
- Price suffix now changes between /month and /year using Alpine.js
- Added € currency symbol to prices
2. Fix language translations:
- Section title/subtitle now fall back to locale files when CMS
content doesn't have translations for the selected language
- Uses cms.platform.pricing.title and .subtitle from locale files
