Changelog Entry

Description

Add pagination support to the /chats/all endpoint to prevent Out of Memory (OOM) errors for users with many chats.

Fixed

Add optional page and limit query parameters to /chats/all endpoint
Set default limit of 1000 to prevent memory exhaustion
Maintain backward compatibility - response is still a list

Added

Pagination parameters for chat list retrieval
Documentation explaining the new parameters

Additional Information

Fixes #22206

Root Cause: Users with thousands of chats were experiencing OOM errors when the /chats/all endpoint tried to load all chats into memory at once.

Solution:

Add optional page and limit query parameters
Default limit of 1000 prevents memory issues
Backward compatible: response format unchanged

Testing:

# Test pagination
GET /chats/all  # Returns max 1000 chats (default limit)
GET /chats/all?page=1&limit=100  # Returns first 100 chats
GET /chats/all?page=2&limit=100  # Returns next 100 chats
