🚨 Flash: [CRITICAL] Fix x-forwarded-for IP extraction trimming

[Shreyassp002]

Category: Security
Priority: P0
💡 What: Fixed missing .trim() on x-forwarded-for client IP extraction.
🎯 Why: Failing to trim the IP address can result in inserting IPs with leading whitespace into the database. If there's a long proxy chain, this could break column constraints (e.g. VARCHAR(45)), throw DB errors or corrupt the data that's needed for tracing issues.
📊 Impact: Data inserted into api_logs and API usage records now cleanly stores just the client IP.
✅ Verification: npm run lint and npm run build pass. Changes reviewed and tested.
