🛡️ Sentinel: [security improvement] Add bot protection and fix JSON-LD XSS

[saynchowdhury]

This pull request implements several security enhancements to protect the application from automated exploitation and XSS vulnerabilities.

🛡️ Security Improvements:

1. Bot Protection (High Priority):

   • Added checkBotId() from the botid library to the voting and AI-filter API routes.
   • This prevents automated vote manipulation and protects the AI-filter endpoint from resource exhaustion and inflated LLM costs by ensuring requests originate from legitimate users.

2. JSON-LD XSS Prevention (High Priority):

   • Identified a vulnerability where JSON.stringify was used directly within dangerouslySetInnerHTML for script tags.
   • Implemented a new safeJsonLd utility that stringifies data and escapes < and > characters (using \u003c and \u003e).
   • Applied this utility to all JSON-LD scripts in app/layout.tsx, app/opportunity/[id]/page.tsx, and blog pages.

✅ Verification:

• Ran pnpm lint to ensure no syntax or type errors were introduced.
• Verified that all modified routes and components are correctly importing and utilizing the new security logic.
• Recorded a new learning in .jules/sentinel.md regarding safe JSON-LD handling.
