Dayuan Jiang ed069afdea fix: use full IP for userId to prevent quota collision (#400)
* fix: use full IP for userId to prevent quota collision

- Remove .slice(0, 8) from base64 encoded IP
- Each IP now has unique userId (no /16 collision)
- Affects: quota tracking, Langfuse tracing

* refactor: extract getUserIdFromRequest to shared utility

- Create lib/user-id.ts with shared function
- Fix misleading 'privacy' comment (base64 is not privacy)
- Remove duplicate code from chat and log-feedback routes
