The extractClientIP() function only checked proxy headers (X-Forwarded-For,
CF-Connecting-IP, etc.) which don't exist when running locally without a proxy.
Changes:
- Add clientIP field to APIContext
- Use Bun's server.requestIP() to get client IP from direct socket connection
- Update getGeoInfo() to accept fallback IP parameter
- Pass context.clientIP to getGeoInfo() in auth procedures
Now sessions will have IP address set even for local development (::1 or 127.0.0.1).
