feat: Add complete i18n translations for AskSaralSeva component

[SomshekharArabali]

📝 Description

This PR adds complete internationalization (i18n) support for the AskSaralSeva AI recommender component, ensuring all text is properly translated between English and Hindi.

Problem

Previously, several text elements in the AskSaralSeva component were hardcoded in English and not translating when users switched languages:

• "AI Beta" badge
• Pro Tips section
• Privacy notice
• Example queries
• AI assistant tooltips
• Initial greeting message not updating on language change

🧪 Testing

• Tested language switching between English and Hindi
• Verified initial greeting updates on language change
• Confirmed all tooltips display in correct language
• Checked Pro Tips section translations
• Validated example queries in both languages
• Tested dynamic scheme count messages (singular/plural)
