📄 Description

Summary

Optimizes the user list API endpoints by preventing large base64 profile image data from being fetched from the database and serialized to JSON responses.

Problem

The /api/v1/users/ endpoint was taking 1.5-2 seconds to return just 30 users because each user's profile_image_url field contained embedded base64 image data (~35KB per user), resulting in ~1MB response payloads.

Solution

Added defer_profile_image parameter to Users.get_users() that uses SQLAlchemy's defer() to exclude the profile_image_url column from database queries
Override profile_image_url in responses with a URL path that points to the existing profile image endpoint

Changes

models/users.py: Add defer_profile_image parameter with defer(User.profile_image_url)
routers/users.py: Pass defer_profile_image=True and override with /api/v1/users/{id}/profile/image

Impact

Metric	Before	After
Response size (30 users)	~1 MB	~5 KB
Database I/O	Fetches ~35KB per user	Skips column

Non-breaking

The frontend already uses the /api/v1/users/{id}/profile/image endpoint for displaying avatars, so this change is transparent to clients.
