feat: add currency, salary period, and rich text description

Frontend:
- Added currency selector (BRL, USD, EUR, JPY, GBP, CNY, AED, CAD, AUD, CHF)
- Added salary period dropdown (hourly, daily, weekly, monthly, yearly)
- Created RichTextEditor component for job descriptions (Bold, Lists, Alignment)
- Updated confirmation step to display currency symbol and period label

Backend:
- JobService now persists currency in job creation
- Extended currency validation in DTOs

Seeder:
- Already includes currency in job insertion
