🛡️ Sentinel: Fix missing bot protection on public POST routes

[saynchowdhury]

🚨 Severity: HIGH
💡 Vulnerability: Public POST routes /api/opportunities/[id]/vote and /api/opportunities/ai-filter were missing bot detection, leaving them vulnerable to automated abuse (vote stuffing and LLM resource exhaustion).
🎯 Impact: Automated manipulation of community rankings and potential for significant LLM API costs from bot traffic.
🔧 Fix: Integrated checkBotId() from botid/server into both route handlers to reject requests from identified bots with a 403 status code.
✅ Verification: Confirmed implementation via read_file, and verified project stability with pnpm lint and pnpm test:run.
